2 BACKGROUND 2.1 Pathobiology of Cancer

Cancer is characterized primarily by an increase in the number of abnormal cells derived from a given normal tissue, invasion of adjacent tissues by these abnormal cells, or lymphatic or blood-borne spread of malignant cells to regional lymph nodes and to distant sites (metastasis). Clinical data and molecular biologic studies indicate that cancer is a multistep process that begins with minor preneoplastic changes, which may under certain conditions progress to neoplasia. The neoplastic lesion may evolve clonally and develop an increasing capacity for invasion, growth, metastasis, and heterogeneity, especially under conditions in which the neoplastic cells escape the host's immune surveillance. Roitt, I., Brostoff, J and Kale, D., Immunology, 17.1-17.12 (3rd ed., Mosby, St. Louis, Mo., 1993).

There is an enormous variety of cancers which are described in detail in the medical literature. Examples include cancers of the lung, colon, rectum, prostate, breast, brain, blood and intestine. The incidence of cancer continues to climb as the general population ages, as new cancers develop, and as susceptible populations (e.g., people infected with AIDS or excessively exposed to sunlight) grow. However, options for the treatment of cancer are limited. For example, in the case of blood cancers (e.g., multiple myeloma), few treatment options are available, especially when conventional chemotherapy fails and bone-marrow transplantation is not an option. A tremendous demand therefore exists for new methods and compositions that can be used to treat patients with cancer.

Many types of cancers are associated with new blood vessel formation, a process known as angiogenesis. Several of the mechanisms involved in tumor-induced angiogenesis have been elucidated. The most direct of these mechanisms is the secretion by the tumor cells of cytokines with angiogenic properties. Examples of these cytokines include acidic and basic fibroblastic growth factor (a,b-FGF), angiogenin, vascular endothelial growth factor (VEGF), and TNF-α. Alternatively, tumor cells can release angiogenic peptides through the production of proteases and the subsequent breakdown of the extracellular matrix where some cytokines are stored (e.g., b-FGF). Angiogenesis can also be induced indirectly through the recruitment of inflammatory cells (particularly macrophages) and their subsequent release of angiogenic cytokines (e.g., TNF-α, b-FGF).

Lymphoma refers to cancers that originate in the lymphatic system. Lymphoma is characterized by malignant neoplasms of lymphocytes—B lymphocytes and T lymphocytes (i.e., B-cells and T-cells). Lymphoma generally starts in lymph nodes or collections of lymphatic tissue in organs including, but not limited to, the stomach or intestines. Lymphoma may involve the marrow and the blood in some cases. Lymphoma may spread from one site to other parts of the body.

The treatments of various forms of lymphomas are described, for example, in U.S. Pat. No. 7,468,363, the entirety of which is incorporated herein by reference. Such lymphomas include, but are not limited to, Hodgkin's lymphoma, non-Hodgkin's lymphoma, cutaneous B-cell lymphoma, activated B-cell lymphoma, DLBCL, mantle cell lymphoma (MCL), follicular center lymphoma, transformed lymphoma, lymphocytic lymphoma of intermediate differentiation, intermediate lymphocytic lymphoma (ILL), diffuse poorly differentiated lymphocytic lymphoma (PDL), centrocytic lymphoma, diffuse small-cleaved cell lymphoma (DSCCL), peripheral T-cell lymphomas (PTCL), cutaneous T-Cell lymphoma and mantle zone lymphoma and low grade follicular lymphoma.

Non-Hodgkin's lymphoma (NHL) is the fifth most common cancer for both men and women in the United States, with an estimated 63,190 new cases and 18,660 deaths in 2007. Jemal A, et al., CA Cancer J Clin 2007; 57(1):43-66. The probability of developing NHL increases with age and the incidence of NHL in the elderly has been steadily increasing in the past decade, causing concern with the aging trend of the U.S. population. Id. Clarke C A, et al., Cancer 2002; 94(7):2015-2023.

DLBCL accounts for approximately one-third of non-Hodgkin's lymphomas. While some DLBCL patients are cured with traditional chemotherapy, the remainders die from the disease. Anticancer drugs cause rapid and persistent depletion of lymphocytes, possibly by direct apoptosis induction in mature T and B cells. See K. Stahnke et al., Blood 2001, 98:3066-3073. Absolute lymphocyte count (ALC) has been shown to be a prognostic factor in follicular non-Hodgkin's lymphoma and recent results have suggested that ALC at diagnosis is an important prognostic factor in DLBCL.

DLBCL can be divided into distinct molecular subtypes according to their gene profiling patterns: germinal-center B-cell-like DLBCL (GCB-DLBCL), activated B-cell-like DLBCL (ABC-DLBCL), and primary mediastinal B-cell lymphoma (PMBL) or unclassified type. These subtypes are characterized by distinct differences in survival, chemo-responsiveness, and signaling pathway dependence, particularly the NF-κB pathway. See D. Kim et al., Journal of Clinical Oncology, 2007 ASCO Annual Meeting Proceedings Part I. Vol 25, No. 18S (June 20 Supplement), 2007: 8082. See Bea S, et al., Blood 2005; 106: 3183-90; Ngo V. N. et al., Nature 2011; 470: 115-9. Such differences have prompted the search for more effective and subtype-specific treatment strategies in DLBCL.

Leukemia refers to malignant neoplasms of the blood-forming tissues. Various forms of leukemias are described, for example, in U.S. Pat. No. 7,393,862 and U.S. provisional patent application No. 60/380,842, filed May 17, 2002, the entireties of which are incorporated herein by reference. Although viruses reportedly cause several forms of leukemia in animals, causes of leukemia in humans are to a large extent unknown. The Merck Manual, 944-952 (17^(th) ed. 1999). Transformation to malignancy typically occurs in a single cell through two or more steps with subsequent proliferation and clonal expansion. In some leukemias, specific chromosomal translocations have been identified with consistent leukemic cell morphology and special clinical features (e.g., translocations of 9 and 22 in chronic myelocytic leukemia, and of 15 and 17 in acute promyelocytic leukemia). Acute leukemias are predominantly undifferentiated cell populations and chronic leukemias more mature cell forms.

Acute leukemias are divided into lymphoblastic (ALL) and non-lymphoblastic (ANLL) types. The Merck Manual, 946-949 (17^(th) ed. 1999). They may be further subdivided by their morphologic and cytochemical appearance according to the French-American-British (FAB) classification or according to their type and degree of differentiation. The use of specific B- and T-cell and myeloid-antigen monoclonal antibodies are most helpful for classification. ALL is predominantly a childhood disease which is established by laboratory findings and bone marrow examination. ANLL, also known as acute myelogenous leukemia or acute myeloid leukemia (AML), occurs at all ages and is the more common acute leukemia among adults; it is the form usually associated with irradiation as a causative agent.

Chronic leukemias are described as being lymphocytic (CLL) or myelocytic (CML). The Merck Manual, 949-952 (17^(th) ed. 1999). CLL is characterized by the appearance of mature lymphocytes in blood, bone marrow, and lymphoid organs. The hallmark of CLL is sustained, absolute lymphocytosis (>5,000/μL) and an increase of lymphocytes in the bone marrow. Most CLL patients also have clonal expansion of lymphocytes with B-cell characteristics. CLL is a disease of middle or old age. In CML, the characteristic feature is the predominance of granulocytic cells of all stages of differentiation in blood, bone marrow, liver, spleen, and other organs. In the symptomatic patient at diagnosis, the total white blood cell (WBC) count is usually about 200,000/μL, but may reach 1,000,000/μL. CML is relatively easy to diagnose because of the presence of the Philadelphia chromosome.

Bone marrow stromal cells are well known to support CLL disease progression and resistance to chemotherapy. Disrupting the interactions between CLL cells and stromal cells is an additional target of CLL chemotherapy.

In addition to the acute and chronic categorization, neoplasms are also categorized based upon the cells giving rise to such disorder into precursor or peripheral. See e.g., U.S. patent Publication No. 2008/0051379, the disclosure of which is incorporated herein by reference in its entirety. Precursor neoplasms include ALLs and lymphoblastic lymphomas and occur in lymphocytes before they have differentiated into either a T- or B-cell. Peripheral neoplasms are those that occur in lymphocytes that have differentiated into either T- or B-cells. Such peripheral neoplasms include, but are not limited to, B-cell CLL, B-cell prolymphocytic leukemia, lymphoplasmacytic lymphoma, mantle cell lymphoma, follicular lymphoma, extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue, nodal marginal zone lymphoma, splenic marginal zone lymphoma, hairy cell leukemia, plasmacytoma, DLBCL and Burkitt lymphoma. In over 95 percent of CLL cases, the clonal expansion is of a B cell lineage. See Cancer: Principles & Practice of Oncology (3rd Edition) (1989) (pp. 1843-1847). In less than 5 percent of CLL cases, the tumor cells have a T-cell phenotype. Notwithstanding these classifications, however, the pathological impairment of normal hematopoiesis is the hallmark of all leukemias.

Multiple myeloma (MM) is a cancer of plasma cells in the bone marrow. Normally, plasma cells produce antibodies and play a key role in immune function. However, uncontrolled growth of these cells leads to bone pain and fractures, anemia, infections, and other complications. Multiple myeloma is the second most common hematological malignancy, although the exact causes of multiple myeloma remain unknown. Multiple myeloma causes high levels of proteins in the blood, urine, and organs, including but not limited to M-protein and other immunoglobulins (antibodies), albumin, and beta-2-microglobulin. M-protein, short for monoclonal protein, also known as paraprotein, is a particularly abnormal protein produced by the myeloma plasma cells and can be found in the blood or urine of almost all patients with multiple myeloma.

Skeletal symptoms, including bone pain, are among the most clinically significant symptoms of multiple myeloma. Malignant plasma cells release osteoclast stimulating factors (including IL-1, IL-6 and TNF) which cause calcium to be leached from bones causing lytic lesions; hypercalcemia is another symptom. The osteoclast stimulating factors, also referred to as cytokines, may prevent apoptosis, or death of myeloma cells. Fifty percent of patients have radiologically detectable myeloma-related skeletal lesions at diagnosis. Other common clinical symptoms for multiple myeloma include polyneuropathy, anemia, hyperviscosity, infections, and renal insufficiency.

Bone marrow stromal cells are well known to support multiple myeloma disease progression and resistance to chemotherapy. Disrupting the interactions between multiple myeloma cells and stromal cells is an additional target of multiple myeloma chemotherapy.

Myelodysplastic syndrome (MDS) refers to a diverse group of hematopoietic stem cell disorders. MDS is characterized by a cellular marrow with impaired morphology and maturation (dysmyelopoiesis), peripheral blood cytopenias, and a variable risk of progression to acute leukemia, resulting from ineffective blood cell production. See The Merck Manual 953 (17th ed. 1999) and List et al., 1990, J Clin. Oncol. 8:1424. The treatment of MDS using immunomodulatory compounds is described in U.S. Patent Publication No. 2004/0220144, the entirety of which is hereby incorporated by reference.

Solid tumors are abnormal masses of tissue that may, but usually do not contain cysts or liquid areas. Solid tumors may be benign (not cancer), or malignant (cancer). Different types of solid tumors are named for the type of cells that form them. Examples of types solid tumors include, but are not limited to malignant melanoma, adrenal carcinoma, breast carcinoma, renal cell cancer, carcinoma of the pancreas, non-small-cell lung carcinoma (NSCLC) and carcinoma of unknown primary. Drugs commonly administered to patients with various types or stages of solid tumors include, but are not limited to, celebrex, etoposide, cyclophosphamide, docetaxel, apecitabine, IFN, tamoxifen, IL-2, GM-CSF, or a combination thereof.

While patients who achieve a complete remission after initial therapy have a good chance for cure, less than 10% of those who do not respond or relapse achieve a cure or a response lasting longer than 3 years. See Cerny T, et al., Ann Oncol 2002; 13 Suppl 4:211-216.

Rituximab is known to deplete normal host B cells. See M. Aklilu et al., Annals of Oncology 15:1109-1114, 2004. The long-term immunologic effects of B cell depletion with rituximab and the characteristics of the reconstituting B cell pool in lymphoma patients are not well defined, despite the widespread usage of this therapy. See Jennifer H. Anolik et al., Clinical Immunology, vol. 122, issue 2, February 2007, pages 139-145.

The approach for patients with relapsed or refractory disease relies heavily on experimental treatments followed by stem cell transplantation, which may not be appropriate for patients with a poor performance status or advanced age. Therefore, a tremendous demand exists for new methods that can be used to treat patients with NHL.

The link between cancer an altered cellular metabolism has been well established. See Cairns, R. A., et al. Nature Rev., 2011, 11:85-95. Understanding tumor cell metabolism and the associated genetic changes thereof may lead to the identification of improved methods of cancer treatment. Id. For example, tumor cell survival and proliferation via increased glucose metabolism has been linked to the PIK3 pathway, whereby mutations in tumor suppressor genes such as PTEN activate tumor cell metabolism. Id. AKT1 (a.k.a., PKB) stimulates glucose metabolism associated with tumor cell growth by various interactions with PFKFB3, ENTPD5, mTOR and TSC2 (a.k.a., tuberin). Id.

Transcription factors HIF1 and HIF2 are largely responsible for cellular response to low oxygen conditions often associated with tumors. Id. Once activated, HIF1 promotes tumor cell capacity to carry out glycolysis. Id. Thus, inhibition of HIF1 may slow or reverse tumor cell metabolism. Activation of HIF1 has been linked to PI3K, tumor suppressor proteins such as VHL, succinate dehydrogenase (SDH) and fumarate hydratase. Id. The oncogenic transcription factor MYC has also been linked to tumor cell metabolism, specifically glycolysis. Id. MYC also promotes cell proliferation by glutamine metabolic pathways. Id.

AMP-activated protein kinase (AMPK) functions as a metabolic check point which tumor cells must overcome in order to proliferate. Id. Several mutations have been identified which suppress AMPK signaling in tumor cells. See Shackelford, D. B. & Shaw, R. J., Nature Rev. Cancer, 2009, 9: 563-575. STK11 has been identified as a tumor suppressor gene related to the role of AMPK. See Cairns, R. A., et al. Nature Rev., 2011, 11:85-95.

The transcription factor p53, a tumor suppressor, also has an important role in the regulation of cellular metabolism. Id. The loss of p53 in tumor cells may be a significant contributor to changes in tumor cell metabolism to the glycolytic pathway. Id. The OCT1 transcription factor, another potential target for chemotherapeutics, may cooperate with p53 in regulating tumor cell metabolism. Id.

Pyruvate kinate M2 (PKM2) promotes changes in cellular metabolism which confer metabolic advantages to cancer cells by supporting cell proliferation. Id. For example, lung cancer cells which express PKM2 over PKM1 have been found to have such an advantage. Id. In the clinic, PKM2 has been identified as being overexpressed in a number of cancer types. Id. Thus PKM2 may be a useful biomarker for the early detection of tumors.

Mutations in isocitrate dehydrogenases IDH1 and IDH2 have been linked to tumorigenesis, specifically, in glioblastoma and acute myeloid leukemia. See Mardis, E. R. et al., N. Engl. J. Med., 2009, 361: 1058-1066; Parsons, D. W. et al., Science, 2008, 321: 1807-1812.

The incidence of cancer continues to climb as the general population ages, as new cancers develop, and as susceptible populations (e.g., people infected with AIDS, the elderly or excessively exposed to sunlight) grow. A tremendous demand therefore exists for new methods, treatments and compositions that can be used to treat patients with cancer including but not limited to those with lymphoma, NHL, multiple myeloma, AML, leukemias, and solid tumors.

A variety of other diseases and disorders are also associated with, or characterized by, undesired angiogenesis. For example, enhanced or unregulated angiogenesis has been implicated in a number of diseases and medical conditions including, but not limited to, ocular neovascular diseases, choroidal neovascular diseases, retina neovascular diseases, rubeosis (neovascularization of the angle), viral diseases, genetic diseases, inflammatory diseases, allergic diseases, fibrosis, arthritis and autoimmune diseases. Examples of such diseases and conditions include, but are not limited to: diabetic retinopathy; retinopathy of prematurity; corneal graft rejection; neovascular glaucoma; retrolental fibroplasia; and proliferative vitreoretinopathy.

Accordingly, compounds that can control and/or inhibit unwanted angiogenesis or inhibit the production of certain cytokines, including TNF-α, may be useful in the treatment and prevention of various diseases and conditions.

2.2 Methods of Treating Cancer

Current cancer therapy may involve surgery, chemotherapy, hormonal therapy and/or radiation treatment to eradicate neoplastic cells in a patient (see, for example, Stockdale, 1998, Medicine, vol. 3, Rubenstein and Federman, eds., Chapter 12, Section IV). Recently, cancer therapy could also involve biological therapy or immunotherapy. All of these approaches may pose significant drawbacks for the patient. Surgery, for example, may be contraindicated due to the health of a patient or may be unacceptable to the patient. Additionally, surgery may not completely remove neoplastic tissue. Radiation therapy is only effective when the neoplastic tissue exhibits a higher sensitivity to radiation than normal tissue. Radiation therapy can also often elicit serious side effects. Hormonal therapy is rarely given as a single agent. Although hormonal therapy can be effective, it is often used to prevent or delay recurrence of cancer after other treatments have removed the majority of cancer cells. Certain biological and other therapies are limited in number and may produce side effects such as rashes or swellings, flu-like symptoms, including fever, chills and fatigue, digestive tract problems or allergic reactions.

With respect to chemotherapy, there are a variety of chemotherapeutic agents available for treatment of cancer. A number of cancer chemotherapeutics act by inhibiting DNA synthesis, either directly or indirectly by inhibiting the biosynthesis of deoxyribonucleotide triphosphate precursors, to prevent DNA replication and concomitant cell division. Gilman et al., Goodman and Gilman's: The Pharmacological Basis of Therapeutics, Tenth Ed. (McGraw Hill, New York).

Despite availability of a variety of chemotherapeutic agents, chemotherapy has many drawbacks. Stockdale, Medicine, vol. 3, Rubenstein and Federman, eds., ch. 12, sect. 10, 1998. Almost all chemotherapeutic agents are toxic, and chemotherapy causes significant and often dangerous side effects including severe nausea, bone marrow depression, and immunosuppression. Additionally, even with administration of combinations of chemotherapeutic agents, many tumor cells are resistant or develop resistance to the chemotherapeutic agents. In fact, those cells resistant to the particular chemotherapeutic agents used in the treatment protocol often prove to be resistant to other drugs, even if those agents act by different mechanism from those of the drugs used in the specific treatment. This phenomenon is referred to as multidrug resistance. Because of the drug resistance, many cancers prove refractory to standard chemotherapeutic treatment protocols.

There exists a significant need for safe and effective methods of treating, preventing and managing cancer, particularly for cancers that are refractory to standard treatments, such as surgery, radiation therapy, chemotherapy and hormonal therapy, while reducing or avoiding the toxicities and/or side effects associated with the conventional therapies. The present invention satisfies these and other needs.

2.3 Cereblon

At least two isoforms of the protein cereblon (CRBN) exist, which are 442 and 441 amino acids long, respectively, and CRBN is conserved from plant to human. In humans, the CRBN gene has been identified as a candidate gene of an autosomal recessive nonsyndromic mental retardation (ARNSMR). See Higgins, J. J. et al., Neurology, 2004, 63:1927-1931. CRBN was initially characterized as an RGS-containing novel protein that interacted with a calcium-activated potassium channel protein (SLO1) in the rat brain, and was later shown to interact with a voltage-gated chloride channel (CIC-2) in the retina with AMPK1 and DDB1. See Jo, S. et al., J. Neurochem, 2005, 94:1212-1224; Hohberger B. et al., FEBS Lett, 2009, 583:633-637; Angers S. et al., Nature, 2006, 443:590-593. DDB1 was originally identified as a nucleotide excision repair protein that associates with damaged DNA binding protein 2 (DDB2). Its defective activity causes the repair defect in the patients with xeroderma pigmentosum complementation group E (XPE). DDB1 also appears to function as a component of numerous distinct DCX (DDB1-CUL4-X-box) E3 ubiquitin-protein ligase complexes which mediate the ubiquitination and subsequent proteasomal degradation of target proteins. CRBN has also been identified as a target for the development of therapeutic agents for diseases of the cerebral cortex. See WO 2010/137547 A1.

CRBN has recently been identified as a key molecular target that binds to thalidomide to cause birth defects. See Ito, T. et al., Science, 2010, 327:1345-1350. DDB1 was found to interact with CRBN and, thus, was indirectly associated with thalidomide. Moreover, thalidomide was able to inhibit auto-ubiquitination of CRBN in vitro, suggesting that thalidomide is an E3 ubiquitin-ligase inhibitor. Id. Importantly, this activity was inhibited by thalidomide in wild-type cells, but not in cells with mutated CRBN binding sites that prevent thalidomide binding. Id. The thalidomide binding site was mapped to a highly conserved C-terminal 104 amino acid region in CRBN. Id. Individual point mutants in CRBN, Y384A and W386A were both defective for thalidomide binding, with the double point mutant having the lowest thalidomide-binding activity. Id. A link between CRBN and the teratogenic effect of thalidomide was confirmed in animal models of zebra-fish and chick embryos. Id.

Whether binding to CRBN, the CRBN E3 ubiquitin-ligase complex, or one or more substrates of CRBN, is required for the beneficial effects of thalidomide and other drugs is yet to be established. Understanding these interactions with thalidomide and other drug targets will allow the definition of the molecular mechanisms of efficacy and/or toxicity and may lead to drugs with improved efficacy and toxicity profiles.

2.4 Compounds

A number of studies have been conducted with the aim of providing compounds that can safely and effectively be used to treat diseases associated with abnormal production of TNF-a. See, e.g., Marriott, J. B., et al., Expert Opin. Biol. Ther., 2001, 1(4): 1-8; G. W. Muller, et al., J Med Chem., 1996, 39(17): 3238-3240; and G. W. Muller, et al., Bioorg & Med Chem Lett., 1998, 8: 2669-2674. Some studies have focused on a group of compounds selected for their capacity to potently inhibit TNF-α production by LPS stimulated PBMC. L. G. Corral, et al., Ann. Rheum. Dis., 1999, 58:(Suppl I) 1107-1113. These compounds show not only potent inhibition of TNF-α but also marked inhibition of LPS induced monocyte IL1β and IL12 production. LPS induced IL6 is also inhibited by such compounds, albeit partially. These compounds are potent stimulators of LPS induced IL10. Id.

Compounds for the methods provided herein include, but are not limited to, the substituted 2-(2,6-dioxopiperidin-3-yl) phthalimides and substituted 2-(2,6-dioxopiperidin-3-yl)-1-oxoisoindoles described in U.S. Pat. Nos. 6,281,230 and 6,316,471, both to G. W. Muller, et al. Still other specific compounds disclosed herein belong to a class of isoindole-imides disclosed in U.S. Pat. Nos. 6,395,754, 6,555,554, 7,091,353, U.S. Publication No. 2004/0029832, and International Publication No. WO 98/54170, each of which is incorporated herein by reference.

Thalidomide, lenalidomide and pomalidomide have shown remarkable responses in patients with multiple myeloma, lymphoma and other hematological diseases such as myelodysplastic syndrome. See Galustian C, et al., Expert Opin Pharmacother., 2009, 10:125-133. These drugs display a broad spectrum of activity, including anti-angiogenic properties, modulation of pro-inflammatory cytokines, co-stimulation of T cells, increased NK cell toxicity, direct anti-tumor effects and modulation of stem cell differentiation.

For example, thalidomide and lenalidomide have emerged as important options for the treatment of multiple myeloma in newly diagnosed patients, in patients with advanced disease who have failed chemotherapy or transplantation, and in patients with relapsed or refractory multiple myeloma. Lenalidomide in combination with dexamethasone has been approved for the treatment of patients with multiple myeloma who have received at least one prior therapy. Pomalidomide may also be administered in combination with dexamethasone. U.S. Patent Publication No. 2004/0029832 A1, the disclosure of which is hereby incorporated in its entirety, discloses the treatment of multiple myeloma.

The conventional methods of assessing the effects of immunomodulatory compounds require live cellular assays or lengthy clinical endpoints. These cellular tests are cumbersome and often require the use of various stimulants (e.g., lipopolysaccharide or anti-CD3 antibody). Indirect endpoints such as cytokine production are evaluated, which can be influenced via multiple pathways. Further, clinical efficacy of these compounds could not be correctly predicted, as it could only be measured in terms of patient response, which usually requires a minimum of several months of treatment. In view of the deficiencies of the conventional methods, there is a need to develop an efficient, sensitive and accurate method to detect, quantify and characterize the pharmacodynamic activity of immunomodulatory compounds.

4 BRIEF DESCRIPTION OF THE FIGURES

FIGS. 1A-C depict that Aiolos and Ikaros are CRBN substrates in ABC and GCB DLBCL. DLBCL cells were treated with DMSO, Lenalidomide or Compound A for 1, 6, 12 or 72 hours and then levels of Aiolos, Ikaros, IRF4 or β-actin were assessed. (A) Lenalidomide and Compound A are biochemically active in both GCB and ABC DLBCL subsets. (B) and (C) Aiolos and Ikaros are substrates of the CRBN complex in DLBCL; and lenalidomide and Compound A reduce IRF4 levels within 72 hours.

FIGS. 2A-B depict that Aiolos and Ikaros are CRL4^(CRBN) substrates in vivo. WSU-DLCL2 xenograft SCID mice were treated with either vehicle or 30 mg/kg Compound A qd. Tumor samples were harvested at indicated time points after last dose. Tissues were then subjected to FFPE IHC for Aiolos, and Ikaros. (A) Compound A induces Aiolos degradation within 6 hours of treatment in WSU-DLCL2 xenograft SCID mice. (B) Compound A induces Ikaros degradation within 6 hours of treatment in WSU-DLCL2 xenograft SCID mice.

FIGS. 3A-C depicts Aiolos is a driver of lymphoma proliferation and regulates c-Myc. Inducible Aiolos shRNA cell lines were treated with 0-100 ng/ml of doxycycline for 72 hours and Aiolos, c-myc, IRF4 or β-actin protein levels were assessed. (A) At least three out of five Aiolos shRNAs result in decreased Aiolos protein levels. (B) and (C) Three Aiolos shRNAs also decrease proliferation and c-Myc levels. Aiolos shRNA results in the significant decrease of c-myc but not IRF4. Proliferation assays indicate that shRNA targeting Aiolos inhibit proliferation of cells at 3 and 5 days post-doxycycline treatment.

FIG. 4A-C depicts the generation of DLBCL cell lines resistant to lenalidomide and Compound A. Cell lines were made resistant to Lenalidomide and Compound A through chronic exposure to both compounds. Proliferation of resistant and parental cells were assessed through tritiated thymidine incorporation assays. (A)-(C) Resistant Lenalidomide (“Len”) or Compound A cell lines demonstrate resistance compared to parental cells after a 10 day washout period indicating resistance was now an inherent trait of the resistant cell.

FIGS. 5A-B depict the resistance to lenalidomide and Compound A mechanism of action. (A) Acquired resistance in DLBCL does not involve downregulation of CRBN levels as is observed in multiple myeloma. However, Aiolos and Ikaros levels are slightly decreased in WSU-DLCL2 resistant cells compared to parental. Additionally, c-Myc levels are decreased in both WSU-DLCL2 and TMD8 resistant cells while CD44, a marker of aggressive disease, is increased in the ABC DLBCL cell line (TMD8). (B) The rate of destruction of Aiolos in the WSU-DLCL2 CmpA-R (Compound A resistant) cell line is decreased compared to the parental cell line.

FIG. 6A-C depict the dynamic range of expression levels of CRBN, Aiolos and Ikaros in DLBCL patients. IHC of a FFPE samples from 90 patients for CRBN, Aiolos and Ikaros indicates a wide range of expression levels in primary DLBCL. (A) Range of CRBN expression in three exemplary clinical trial patients, C4, F2 and B9. CRBN staining was observed in 76/90 cases (84%). Nuclear CRBN was observed in 23/76 positive CRBN tumors. (B) Range of Aiolos expression in two exemplary clinical trial patients, E2 and G4. Aiolos staining was observed in 85/90 cases (94%). Aiolos was strongly expressed in 61/85 patients. (C) Range of Ikaros expression in two exemplary clinical trial patients, E2 and G4. Ikaros staining was observed in 76/90 cases (84%). The dynamic range of CRBN, Aiolos and Ikaros in DLBCL can be used as a positive inclusion process for participation in a Compound A (or other compound) clinical trial.

FIGS. 7A-C depict the differential activity of lenalidomide and Compound A in GCB and ABC DLBCL. Multiple DLBCL cell lines were culture with either Lenalidomide or COMPOUND A for 3 days. Proliferation was assessed through tritiated thymidine incorporation. Three phenomena were observed; inherent resistance, differential activity of COMPOUND A compared to Lenalidomide or a distinct potency difference between the two molecules. (A) and (B) Differential activity of Compound A is observed in some GCB DLBCL compared to lenalidomide. (C) Compound A is more potent than lenalidomide in ABC DLBCL

FIGS. 8A-B depict lenalidomide competes with Compound A and 1-(3-chloro-4-methylphenyl)-3-((2-(2,6-dioxopiperidin-3-yl)-1-oxoisoindolin-5-yl)methyl)urea (“Compound C” or Cmp C) for CRBN. (A) and (B) Co-treatment of lenalidomide with either Compound A or Compound C blocks the anti-proliferative effects of either drug through competition of binding to the CRBN complex in both ABC and GCB DLBCL. Co-culture of Lenalidomide with either Compound A or Compound C dampens the activity of these compounds as they target the same binding pocket with relative affinity.

FIG. 9 depicts the differentiation of lenalidomide and Compound A in DLBCL using TMT mass spectrometry. GCB and ABC cell lines were treated with either lenalidomide or Compound A for 24 and 72 hours. Aiolos protein levels were analyzed and shown to decrease in a dose-dependent manner in as little as 24 hours in both ABC and GCB DLBCL (bottom panels). Proteins from these cells can also be labeled and analyzed with tandem mass Tag proteomics for signature responses (top panels).

FIGS. 10A-B show IFN pathway protein responses. FIG. 10A shows that Compound A up-regulates IFN response gene expression and upregulates IRF7 protein expression. FIG. 10B shows that shAiolos upregulates IRF7 protein expression.

FIG. 11 shows that CSNK1A1 protein is one of few proteins affected by lenalidomide exposure to a manifestly greater extent than by Compound A.

FIG. 12 illustrates a list of IFN pathway proteins that can be affected by exposure to Compound A and/or lenalidomide.

FIG. 13A-G depict the effect of lenalidomide, pomalidomide, or Compound A on IFN pathway. FIG. 13A shows that lenalidomide, pomalidomide, or Compound A upregulates IFIT1, IFIT3, DDX58, XAF1, IFIH1, and OAS3 protein expression. FIG. 13B shows that lenalidomide, pomalidomide, or Compound A upregulates DDX58, IFI27, IFIT1, IFIT3, DDX58, and XAF1 gene expression. FIG. 13C shows that lenalidomide, pomalidomide, or Compound A upregulates ISG15 and OAS3 gene expression.

FIG. 26 shows that lenalidomide treatment decreases both CSNK1A1 and Ikaros proteins levels at 3 h or 6 h, and pre-treating HNT-34 cells with the proteasome inhibitor MG-132 stabilizes CSNK1A1 protein levels in the presence of lenalidomide.

FIGS. 27A-B shows data for a mechanism of lenalidomide-mediated reduction of CK1α levels. FIG. 27A shows that pre-treating HNT-34 cells with Compound A blocks lenalidomide induced CSNK1A1 degradation. FIG. 27B shows that the LEN-mediated reduction of CK1α levels are cullin-dependent and CRBN-dependent. For example, pretreatment with proteosome inhibitor (MG-132) and neddylation inhibitor (MLN-4924) abrogated LEN-mediated CK1α reduction in HNT-34 cells (FIG. 27B, left panel). In addition, pretreatment with CRBN RNAi inhibited LEN-mediated CK1α reduction in HNT-34 cells (FIG. 27B, right panel).

5 DETAILED DESCRIPTION OF THE INVENTION

The methods, arrays, probes, and kits provided herein are based, in part, on the finding that a changed level, e.g., an increased level and/or a decreased level, of certain molecules (e.g., mRNAs, cDNAs, or proteins) in a biological sample can be utilized as biomarkers to predict responsiveness of a subject having or suspected to have a cancer (e.g., DLBCL, MM, MDS or AML) to a treatment compound (e.g., thalidomide, lenalidomide, pomalidomide, Compound A, or Compound B, or a stereoisomer thereof, or a pharmaceutically acceptable salt, solvate, hydrate, co-crystal, clathrate, or a polymorph thereof).

5.1 Definitions

As used herein, and unless otherwise specified, the terms “treat,” “treating” and “treatment” refer to an action that occurs while a patient is suffering from the specified cancer, which reduces the severity of the cancer, or retards or slows the progression of the cancer.

The term “sensitivity” and “sensitive” when made in reference to treatment with compound is a relative term which refers to the degree of effectiveness of the compound in lessening or decreasing the progress of a tumor or the disease being treated. For example, the term “increased sensitivity” when used in reference to treatment of a cell or tumor in connection with a compound refers to an increase of, at least a 5%, or more, in the effectiveness of the tumor treatment.

As used herein, the terms “compound” and “treatment compound” are used interchangeably, and include immunomodulatory compound or immunomodulatory drug. As used herein, the term “immunomodulatory compound” or “immunomodulatory drug” refers generally to a molecule or agent capable of altering the immune response in some way. Non-limiting examples of immunomodulatory compounds include those disclosed in Section 5.7 below.

As used herein, and unless otherwise specified, the term “therapeutically effective amount” of a compound is an amount sufficient to provide a therapeutic benefit in the treatment or management of a cancer, or to delay or minimize one or more symptoms associated with the presence of the cancer. A therapeutically effective amount of a compound means an amount of therapeutic agent, alone or in combination with other therapies, which provides a therapeutic benefit in the treatment or management of the cancer. The term “therapeutically effective amount” can encompass an amount that improves overall therapy, reduces or avoids symptoms or causes of cancer, or enhances the therapeutic efficacy of another therapeutic agent. The term also refers to the amount of a compound that is sufficient to elicit the biological or medical response of a biological molecule (e.g., a protein, enzyme, RNA, or DNA), cell, tissue, system, animal, or human, which is being sought by a researcher, veterinarian, medical doctor, or clinician.

The term “responsiveness” or “responsive” when used in reference to a treatment refer to the degree of effectiveness of the treatment in lessening or decreasing the symptoms of a disease, e.g., DLBCL, MM, MDS or AML, being treated. For example, the term “increased responsiveness” when used in reference to a treatment of a cell or a subject refers to an increase in the effectiveness in lessening or decreasing the symptoms of the disease when measured using any methods known in the art. In certain embodiments, the increase in the effectiveness is at least about 5%, at least about 10%, at least about 20%, at least about 30%, at least about 40%, or at least about 50%.

As used herein, the terms “effective subject response,” “effective patient response,” or “effective patient tumor response” refers to any increase in the therapeutic benefit to the patient. An “effective patient tumor response” can be, for example, a 5%, 10%, 15%, 20%, 25%, 30%, 40%, 50%, 60%, 70%, 80%, 90%,or 100% decrease in the rate of progress of the tumor. An “effective patient tumor response” can be, for example, a 5%, 10%, 15%, 20%, 25%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, or 100% decrease in the physical symptoms of a cancer. An “effective patient tumor response” can be, for example, a 5%, 10%, 15%, 20%, 25%, 30%, 40%, 50%, 60%, 70%, 80%, 90%,or 100% decrease in the size of a tumor. An “effective patient tumor response” can be, for example, a 5%, 10%, 15%, 20%, 25%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, or 100% decrease in the physical symptoms of a cancer. An “effective patient tumor response” can also be, for example, a 5%, 10%, 15%, 20%, 25%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, 200%, or more increase in the response of the patient, as measured by any suitable means, such as gene expression, cell counts, assay results, etc.

An improvement in the cancer or cancer-related disease can be characterized as a complete or partial response. “Complete response” refers to an essential absence of clinically detectable disease with normalization of any previously abnormal radiographic studies, bone marrow, and cerebrospinal fluid (CSF) or abnormal monoclonal protein measurements. “Partial response” refers to at least about a 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85% or 90% decrease in all measurable tumor burden (i.e., the number of malignant cells present in the subject, or the measured bulk of tumor masses or the quantity of abnormal monoclonal protein) in the absence of new lesions. The term “treatment” contemplates both a complete and a partial response.

The term “likelihood” generally refers to an increase in the probability of an event. The term “likelihood” when used in reference to the effectiveness of a patient tumor response generally contemplates an increased probability that the rate of tumor progress or tumor cell growth will decrease. The term “likelihood” when used in reference to the effectiveness of a patient tumor response can also generally mean the increase of indicators, such as mRNA or protein expression, that may evidence an increase in the progress in treating the tumor.

The term “predict” generally means to determine or tell in advance. When used to “predict” the effectiveness of a cancer treatment, for example, the term “predict” can mean that the likelihood of the outcome of the cancer treatment can be determined at the outset, before the treatment has begun, or before the treatment period has progressed substantially.

The term “monitor,” as used herein, generally refers to the overseeing, supervision, regulation, watching, tracking, or surveillance of an activity. For example, the term “monitoring the effectiveness of a compound” refers to tracking the effectiveness in treating a cancer in a patient or in a tumor cell culture. Similarly, the “monitoring,” when used in connection with patient compliance, either individually, or in a clinical trial, refers to the tracking or confirming that the patient is actually taking a drug being tested as prescribed. The monitoring can be performed, for example, by following the expression of mRNA or protein biomarkers.

An improvement in the cancer or cancer-related disease can be characterized as a complete or partial response. “Complete response” refers to an absence of clinically detectable disease with normalization of any previously abnormal radiographic studies, bone marrow, and cerebrospinal fluid (CSF) or abnormal monoclonal protein measurements. “Partial response” refers to at least about a 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, or 90% decrease in all measurable tumor burden (i.e., the number of malignant cells present in the subject, or the measured bulk of tumor masses or the quantity of abnormal monoclonal protein) in the absence of new lesions. The term “treatment” contemplates both a complete and a partial response.

“Tumor,” as used herein, refers to all neoplastic cell growth and proliferation, whether malignant or benign, and all pre-cancerous and cancerous cells and tissues. “Neoplastic,” as used herein, refers to any form of dysregulated or unregulated cell growth, whether malignant or benign, resulting in abnormal tissue growth. Thus, “neoplastic cells” include malignant and benign cells having dysregulated or unregulated cell growth.

As used herein, the term “cereblon-associated protein” or “CAP” refers to a protein that interacts with or binds to CRBN, either directly or indirectly. For example, the term refers to any protein that directly bind to cereblon, as well as any protein that is an indirect downstream effector of cereblon pathways. In certain embodiments, a “cereblon-associated protein” or “CAP” is a substrate of CRBN, for example, a protein substrate of the E3 ubiquitin ligase complex involving CRBN, or the downstream substrates thereof. In one embodiment, the CAP provided herein is a substrate of CRBN such as IKZF3, also known as “Aiolos,” and/or IKZF1, also known as “Ikaros.” In certain embodiments, a “cereblon-associated protein” or “CAP” is a binding protein of CRBN. In yet other embodiments, the CAP is IFN. In other embodiments, the CAP is an IFN pathway protein listed in FIG. 12. In other embodiment, the IFN pathway protein is IFN-induced transmembrane protein 3 (IFITM3) and/or IFN regulatory factor 7 (IRF7). In yet other embodiments, the CAP is CSNK1A1. In yet other embodiments, the CAP is IFN-induced protein with IFIT3, DDX58, XAF1, IFIH1, OAS3, IFI27, IFIT1, or ISG15. In other embodiments, the CAP is an IRF. In one embodiment, the IRF is selected from a group consisting of IRF1, IRF3, IRF4, IRF7, and IRF9. In other embodiments, the CAP is TBK1 or TBK1-PO4. In other embodiments, the CAP is a STAT proteins or a phosphorylated STAT. In some embodiments, the CAP is ZNF198. Other exemplary CAPs are provided elsewhere herein.

The term “regulate” as used herein refers to controlling the activity of a molecule or biological function, such as enhancing or diminishing the activity or function.

The terms “cancer” and “cancerous” refer to or describe the physiological condition in mammals that is typically characterized by unregulated cell growth. Examples of cancer include, but are not limited to, blood-borne tumors (e.g., multiple myeloma, lymphoma and leukemia), and solid tumors.

The term “refractory or resistant” refers to a circumstance where patients, even after intensive treatment, have residual cancer cells (e.g., leukemia or lymphoma cells) in their lymphatic system, blood and/or blood forming tissues (e.g., marrow).

As used herein the terms “polypeptide” and “protein” as used interchangeably herein, refer to a polymer of amino acids of three or more amino acids in a serial array, linked through peptide bonds. The term “polypeptide” includes proteins, protein fragments, protein analogues, oligopeptides and the like. The term polypeptide as used herein can also refer to a peptide. The amino acids making up the polypeptide may be naturally derived, or may be synthetic. The polypeptide can be purified from a biological sample. The polypeptide, protein, or peptide also encompasses modified polypeptides, proteins, and peptides, e.g., a glycopolypeptide, glycoprotein, or glycopeptide; or a lipopolypeptide, lipoprotein, or lipopeptide.

The term “antibody” is used herein in the broadest sense and covers fully assembled antibodies, antibody fragments which retain the ability to specifically bind to the antigen (e.g., Fab, F(ab′)₂, Fv, and other fragments), single chain antibodies, diabodies, antibody chimeras, hybrid antibodies, bispecific antibodies, humanized antibodies, and the like. The term “antibody” covers both polyclonal and monoclonal antibodies. The term “antibody” and “immunoglobulin” or “Ig” may be used interchangeably herein. The terms “antibodies that immunospecifically bind to a CRBN antigen,” “antibodies that immunospecifically bind to a CRBN epitope,” “CRBN antibodies,” “anti-CRBN antibodies” and analogous terms are also used interchangeably herein and refer to antibodies and fragments thereof, that specifically bind to a CRBN polypeptide, such as a CRBN antigen or epitope (e.g., peptide 65-76 human CRBN). The antibodies, including both modified antibodies (i.e., antibodies that comprise a modified IgG (e.g., IgG1) constant domain and unmodified antibodies (i.e., antibodies that do not comprise a modified IgG (e.g., IgG1) constant domain that specifically bind to a CRBN polypeptide. An antibody or a fragment thereof that immunospecifically binds to a CRBN antigen may be cross-reactive with related antigens. In certain embodiments, an antibody or a fragment thereof that immunospecifically binds to a CRBN antigen does not cross-react with other antigens. An antibody or a fragment thereof that immunospecifically binds to a CRBN antigen can be identified, for example, by immunoassays, BIAcore, or other techniques known to those of skill in the art. An antibody or a fragment thereof binds specifically to a CRBN antigen when it binds to a CRBN antigen with higher affinity than to any cross-reactive antigen as determined using experimental techniques, such as radioimmunoassays (RIA) and enzyme-linked immunosorbent assays (ELISAs). Typically a specific or selective reaction will be at least twice background signal or noise and more typically more than 10 times background. See, e.g., Paul, ed., 1989, Fundamental Immunology Second Edition, Raven Press, New York at pages 332-336 for a discussion regarding antibody specificity.

Antibodies provided herein include, but are not limited to, synthetic antibodies, monoclonal antibodies, recombinantly produced antibodies, multispecific antibodies (including bi-specific antibodies), human antibodies, humanized antibodies, chimeric antibodies, intrabodies, single-chain Fvs (scFv) (e.g., including monospecific, bispecific, etc.), camelized antibodies, Fab fragments, F(ab″) fragments, disulfide-linked Fvs (sdFv), anti-idiotypic (anti-Id) antibodies, and epitope-binding fragments of any of the above. In particular, antibodies provided herein include immunoglobulin molecules and immunologically active portions of immunoglobulin molecules, i.e., antigen binding domains or molecules that contain an antigen-binding site that immunospecifically binds to a CRBN antigen (e.g., one or more complementarity determining regions (CDRs) of an anti-CRBN antibody). The antibodies provided herein can be of any type (e.g., IgG, IgE, IgM, IgD, IgA and IgY), any class (e.g., IgG1, IgG2, IgG3, IgG4, IgA1 and IgA2), or any subclass (e.g., IgG2a and IgG2b) of immunoglobulin molecule. In some embodiments, the anti-CRBN antibodies are fully human, such as fully human monoclonal CRBN antibodies. In certain embodiments, antibodies provided herein are IgG antibodies, or a class (e.g., human IgG1 or IgG4) or subclass thereof.

The term “antigen binding domain,” “antigen binding region,” “antigen binding fragment,” and similar terms refer to that portion of an antibody which comprises the amino acid residues that interact with an antigen and confer on the binding agent its specificity and affinity for the antigen (e.g., the CDR). The antigen binding region can be derived from any animal species, such as rodents (e.g., rabbit, rat or hamster) and humans. In some embodiments, the antigen binding region will be of human origin.

The term “constant region” or “constant domain” of an antibody refers to a carboxy terminal portion of the light and heavy chain which is not directly involved in binding of the antibody to antigen but exhibits various effector function, such as interaction with the Fc receptor. The terms refer to the portion of an immunoglobulin molecule having a more conserved amino acid sequence relative to the other portion of the immunoglobulin, the variable domain, which contains the antigen binding site. The constant domain contains the CH1, CH2 and CH3 domains of the heavy chain and the CL domain of the light chain.

The term “epitope” as used herein refers to a localized region on the surface of an antigen, such as CRBN polypeptide or CRBN polypeptide fragment, that is capable of being bound to one or more antigen binding regions of an antibody, and that has antigenic or immunogenic activity in an animal, such as a mammal (e.g., a human), that is capable of eliciting an immune response. An epitope having immunogenic activity is a portion of a polypeptide that elicits a antibody response in an animal. An epitope having antigenic activity is a portion of a polypeptide to which an antibody immunospecifically binds as determined by any method well known in the art, for example, by the immunoassays described herein. Antigenic epitopes need not necessarily be immunogenic. Epitopes usually consist of chemically active surface groupings of molecules such as amino acids or sugar side chains and have specific three dimensional structural characteristics as well as specific charge characteristics. A region of a polypeptide contributing to an epitope may be contiguous amino acids of the polypeptide or the epitope may come together from two or more non-contiguous regions of the polypeptide. The epitope may or may not be a three-dimensional surface feature of the antigen.

The terms “fully human antibody” or “human antibody” are used interchangeably herein and refer to an antibody that comprises a human variable region and, in some embodiments, a human constant region. In specific embodiments, the terms refer to an antibody that comprises a variable region and constant region of human origin. “Fully human” anti-CRBN antibodies, in certain embodiments, can also encompass antibodies which bind CRBN polypeptides and are encoded by nucleic acid sequences which are naturally occurring somatic variants of human germline immunoglobulin nucleic acid sequence. In a specific embodiment, the anti-CRBN antibodies provided herein are fully human antibodies. The term “fully human antibody” includes antibodies having variable and constant regions corresponding to human germline immunoglobulin sequences as described by Kabat et al., Sequences of Proteins of Immunological Interest, Fifth Edition, U.S. Department of Health and Human Services, NIH Publication No. 91-3242, 1991.

The phrase “recombinant human antibody” includes human antibodies that are prepared, expressed, created or isolated by recombinant means, such as antibodies expressed using a recombinant expression vector transfected into a host cell, antibodies isolated from a recombinant, combinatorial human antibody library, antibodies isolated from an animal (e.g., a mouse or cow) that is transgenic and/or transchromosomal for human immunoglobulin genes (see, e.g., Taylor, L. D. et al. (1992) Nucl. Acids Res. 20:6287-6295) or antibodies prepared, expressed, created or isolated by any other means that involves splicing of human immunoglobulin gene sequences to other DNA sequences. Such recombinant human antibodies can have variable and constant regions derived from human germline immunoglobulin sequences. See Kabat, E. A. et al. (1991) Sequences of Proteins of Immunological Interest, Fifth Edition, U.S. Department of Health and Human Services, NIH Publication No. 91-3242. In certain embodiments, however, such recombinant human antibodies are subjected to in vitro mutagenesis (or, when an animal transgenic for human Ig sequences is used, in vivo somatic mutagenesis) and thus the amino acid sequences of the VH and VL regions of the recombinant antibodies are sequences that, while derived from and related to human germline VH and VL sequences, may not naturally exist within the human antibody germline repertoire in vivo.

The term “heavy chain” when used in reference to an antibody refers to five distinct types, called alpha (α), delta (δ), epsilon (ε), gamma (γ) and mu (μ), based on the amino acid sequence of the heavy chain constant domain. These distinct types of heavy chains are well known and give rise to five classes of antibodies, IgA, IgD, IgE, IgG and IgM, respectively, including four subclasses of IgG, namely IgG1, IgG1, IgG3 and IgG4. In some embodiments the heavy chain is a human heavy chain.

The terms “Kabat numbering,” and like terms are recognized in the art and refer to a system of numbering amino acid residues which are more variable (i.e. hypervariable) than other amino acid residues in the heavy and light chain variable regions of an antibody, or an antigen binding portion thereof. Kabat et al. (1971) Ann. any Acad. Sci. 190:382-391 and, Kabat et al. (1991) Sequences of Proteins of Immunological Interest, Fifth Edition, U.S. Department of Health and Human Services, NIH Publication No. 91-3242. For the heavy chain variable region, the hypervariable region typically ranges from amino acid positions 31 to 35 for CDR1, amino acid positions 50 to 65 for CDR2, and amino acid positions 95 to 102 for CDR3. For the light chain variable region, the hypervariable region typically ranges from amino acid positions 24 to 34 for CDR1, amino acid positions 50 to 56 for CDR2, and amino acid positions 89 to 97 for CDR3. Other numbering schemes will be readily understood by those skilled in the art.

The term “light chain” when used in reference to an antibody refers to two distinct types, called kappa (κ) of lambda (λ) based on the amino acid sequence of the constant domains. Light chain amino acid sequences are well known in the art. In certain embodiments, the light chain is a human light chain.

The term “monoclonal antibody” refers to an antibody obtained from a population of homogenous or substantially homogeneous antibodies, and each monoclonal antibody will typically recognize a single epitope on the antigen. In some embodiments, a “monoclonal antibody,” as used herein, is an antibody produced by a single hybridoma or other cell, wherein the antibody immunospecifically binds to only a CRBN epitope as determined, e.g., by ELISA or other antigen-binding or competitive binding assay known in the art or in the Examples provided herein. The term “monoclonal” is not limited to any particular method for making the antibody. For example, monoclonal antibodies provided herein may be made by the hybridoma method as described in Kohler et al.; Nature, 256:495 (1975) or may be isolated from phage libraries using the techniques as described herein, for example. Other methods for the preparation of clonal cell lines and of monoclonal antibodies expressed thereby are well known in the art. See, e.g., Chapter 11 in: Short Protocols in Molecular Biology, (2002) 5th Ed., Ausubel et al., eds., John Wiley and Sons, New York. Other exemplary methods of producing other monoclonal antibodies are provided in the Examples herein.

“Polyclonal antibodies” as used herein refers to an antibody population generated in an immunogenic response to a protein having many epitopes and thus includes a variety of different antibodies directed to the same and to different epitopes within the protein. Methods for producing polyclonal antibodies are known in the art. See, e.g., Chapter 11 in: Short Protocols in Molecular Biology, (2002) 5th Ed., Ausubel et al., eds., John Wiley and Sons, New York.

The terms “cereblon” or “CRBN” and similar terms refers to the polypeptides (“polypeptides,” “peptides” and “proteins” are used interchangeably herein) comprising the amino acid sequence any CRBN, such as a human CRBN protein (e.g., human CRBN isoform 1, GenBank Accession No. NP_057386; or human CRBN isoforms 2, GenBank Accession No. NP_001166953, each of which is herein incorporated by reference in its entirety), and related polypeptides, including SNP variants thereof. Related CRBN polypeptides include allelic variants (e.g., SNP variants); splice variants; fragments; derivatives; substitution, deletion, and insertion variants; fusion polypeptides; and interspecies homologs, which, in certain embodiments, retain CRBN activity and/or are sufficient to generate an anti-CRBN immune response.

The term “CRBN antigen” refers to that portion of a CRBN polypeptide to which an antibody immunospecifically binds. A CRBN antigen also refers to an analog or derivative of a CRBN polypeptide or fragment thereof to which an antibody immunospecifically binds. A localized region on the surface of a CRBN antigen that is capable of eliciting an immune response is an CRBN “epitope.” A region of a CRBN polypeptide contributing to an epitope may be contiguous amino acids of the polypeptide or the epitope may come together from two or more non-contiguous regions of the polypeptide. The epitope may or may not be a three-dimensional surface feature of the antigen.

The term “variable region” or “variable domain” refers to a portion of the light and heavy chains, typically about the amino-terminal 120 to 130 amino acids in the heavy chain and about 100 to 110 amino acids in the light chain, which differ extensively in sequence among antibodies and are used in the binding and specificity of each particular antibody for its particular antigen. The variability in sequence is concentrated in those regions called complimentarily determining regions (CDRs) while the more highly conserved regions in the variable domain are called framework regions (FR). The CDRs of the light and heavy chains are primarily responsible for the interaction of the antibody with antigen. Numbering of amino acid positions used herein is according to the EU Index, as in See Kabat, E. A. et al. (1991) Sequences of Proteins of Immunological Interest, Fifth Edition, U.S. Department of Health and Human Services, NIH Publication No. 91-3242. In some embodiments, the variable region is a human variable region.

The term “expressed” or “expression” as used herein refers to the transcription from a gene to give an RNA nucleic acid molecule at least complementary in part to a region of one of the two nucleic acid strands of the gene. The term “expressed” or “expression” as used herein also refers to the translation from the RNA molecule to give a protein, a polypeptide or a portion thereof.

The term “level” refers to the amount, accumulation, or rate of a biomarker molecule. A level can be represented, for example, by the amount or the rate of synthesis of a massager RNA (mRNA) encoded by a gene, the amount or the rate of synthesis of a polypeptide or protein encoded by a gene, or the amount or the rate of synthesis of a biological molecule accumulated in a cell or biological fluid. The term “level” refers to an absolute amount of a molecule in a sample or to a relative amount of the molecule, determined under steady-state or non-steady-state conditions.

An mRNA that is “upregulated” is generally increased upon a given treatment or condition. An mRNA that is “downregulated” generally refers to a decrease in the level of expression of the mRNA in response to a given treatment or condition. In some situations, the mRNA level can remain unchanged upon a given treatment or condition. An mRNA from a patient sample can be “upregulated” when treated with a drug, as compared to a non-treated control. This upregulation can be, for example, an increase of about 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 90%, 100%, 200%, 300%, 500%, 600%, 700%, 800%, 900%, 1,000%, 1,500%, 2,000%, 2,500%, 3,00%, 3,500%, 4,000%, 4,500%, 5,000% or more of the comparative control mRNA level. Alternatively, an mRNA can be “downregulated”, or expressed at a lower level, in response to administration of certain compounds or other agents. A downregulated mRNA can be, for example, present at a level of about 99%, 95%, 90%, 85%, 80%, 75%, 70%, 65%, 60%, 55%, 50%, 45%, 40%, 35%, 30%, 25%, 20%, 15%, 10%, 5%, 3%, 1% or less of the comparative control mRNA level.

Similarly, the level of a polypeptide or protein biomarker from a patient sample can be increased when treated with a drug, as compared to a non-treated control. This increase can be about 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, 200%, 300%, 400%, 500%, 700%, 1,000%, 1,500%, 2,000%, 2,500%, 3,000%, 3,500%, 4,000%, 4,500%, 5,000% or more of the comparative control protein level. Alternatively, the level of a protein biomarker can be decreased in response to administration of certain compounds or other agents. This decrease can be, for example, present at a level of about 99%, 95%, 90%, 80%, 70%, 60%, 50%, 40%, 30%, 20%, 10%, 5%, 3%, 1% or less of the comparative control protein level.

The terms “determining”, “measuring”, “evaluating”, “assessing” and “assaying” as used herein generally refer to any form of measurement, and include determining if an element is present or not. These terms include both quantitative and/or qualitative determinations. Assessing may be relative or absolute. “Assessing the presence of” can include determining the amount of something present, as well as determining whether it is present or absent.

The term “monitor,” as used herein, generally refers to the overseeing, supervision, regulation, watching, tracking, or surveillance of an activity. For example, the term “monitoring the effectiveness of a compound” refers to tracking the effectiveness in treating a cancer in a patient or in a tumor cell culture.

The monitoring can be performed, for example, by following the expression of mRNA or protein biomarkers.

The terms “nucleic acid” and “polynucleotide” are used interchangeably herein to describe a polymer of any length composed of nucleotides, e.g., deoxyribonucleotides or ribonucleotides, or compounds produced synthetically, which can hybridize with naturally occurring nucleic acids in a sequence specific manner analogous to that of two naturally occurring nucleic acids, e.g., can participate in Watson-Crick base pairing interactions. As used herein in the context of a polynucleotide sequence, the term “bases” (or “base”) is synonymous with “nucleotides” (or “nucleotide”), i.e., the monomer subunit of a polynucleotide. The terms “nucleoside” and “nucleotide” are intended to include those moieties that contain not only the known purine and pyrimidine bases, but also other heterocyclic bases that have been modified. Such modifications include methylated purines or pyrimidines, acylated purines or pyrimidines, alkylated riboses or other heterocycles. In addition, the terms “nucleoside” and “nucleotide” include those moieties that contain not only conventional ribose and deoxyribose sugars, but other sugars as well. Modified nucleosides or nucleotides also include modifications on the sugar moiety, e.g., wherein one or more of the hydroxyl groups are replaced with halogen atoms or aliphatic groups, or are functionalized as ethers, amines, or the like. “Analogues” refer to molecules having structural features that are recognized in the literature as being mimetics, derivatives, having analogous structures, or other like terms, and include, for example, polynucleotides incorporating non-natural nucleotides, nucleotide mimetics such as 2′-modified nucleosides, peptide nucleic acids, oligomeric nucleoside phosphonates, and any polynucleotide that has added substituent groups, such as protecting groups or linking moieties.

The term “complementary” refers to specific binding between polynucleotides based on the sequences of the polynucleotides. As used herein, a first polynucleotide and a second polynucleotide are complementary if they bind to each other in a hybridization assay under stringent conditions, e.g. if they produce a given or detectable level of signal in a hybridization assay. Portions of polynucleotides are complementary to each other if they follow conventional base-pairing rules, e.g. A pairs with T (or U) and G pairs with C, although small regions (e.g. less than about 3 bases) of mismatch, insertion, or deleted sequence may be present.

“Sequence identity” or “identity” in the context of two nucleic acid sequences refers to the residues in the two sequences which are the same when aligned for maximum correspondence over a specified comparison window, and can take into consideration additions, deletions and substitutions.

Another indication that nucleotide sequences are substantially identical is if two molecules hybridize to each other under stringent conditions.

The terms “isolated” and “purified” refer to isolation of a substance (such as mRNA, antibody or protein) such that the substance comprises a substantial portion of the sample in which it resides, i.e. greater than the substance is typically found in its natural or un-isolated state.

As used herein, the term “bound” can be used herein to indicate direct or indirect attachment. In the context of chemical structures, “bound” (or “bonded”) may refer to the existence of a chemical bond directly joining two moieties or indirectly joining two moieties (e.g., via a linking group or any other intervening portion of the molecule). The chemical bond may be a covalent bond, an ionic bond, a coordination complex, hydrogen bonding, van der Waals interactions, or hydrophobic stacking, or may exhibit characteristics of multiple types of chemical bonds. In certain instances, “bound” includes embodiments where the attachment is direct and also embodiments where the attachment is indirect.

The term “probe” as used herein, refers to a capture agent that is directed to a specific target mRNA biomarker sequence. Accordingly, each probe of a probe set has a respective target mRNA biomarker. A probe/target mRNA duplex is a structure formed by hybridizing a probe to its target mRNA biomarker.

The term “nucleic acid probe” or “oligonucleotide probe” refers to a nucleic acid capable of binding to a target nucleic acid of complementary sequence, such as the mRNA biomarkers provided herein, through one or more types of chemical bonds, usually through complementary base pairing, usually through hydrogen bond formation. As used herein, a probe may include natural (e.g., A, G, C, or T) or modified bases (7-deazaguanosine, inosine, etc.). In addition, the bases in a probe may be joined by a linkage other than a phosphodiester bond, so long as it does not interfere with hybridization. It will be understood by one of skill in the art that probes may bind target sequences lacking complete complementarity with the probe sequence depending upon the stringency of the hybridization conditions. The probes are preferably directly labeled with isotopes, for example, chromophores, lumiphores, chromogens, or indirectly labeled with biotin to which a streptavidin complex may later bind. By assaying for the presence or absence of the probe, one can detect the presence or absence of a target mRNA biomarker of interest.

The term “stringent assay conditions” refers to conditions that are compatible to produce binding pairs of nucleic acids, e.g., probes and target mRNAs, of sufficient complementarity to provide for the desired level of specificity in the assay while being generally incompatible to the formation of binding pairs between binding members of insufficient complementarity to provide for the desired specificity. The term stringent assay conditions generally refers to the combination of hybridization and wash conditions.

A “label” or a “detectable moiety” in reference to a nucleic acid, refers to a composition that, when linked with a nucleic acid, renders the nucleic acid detectable, for example, by spectroscopic, photochemical, biochemical, immunochemical, or chemical means. Exemplary labels include, but are not limited to, radioactive isotopes, magnetic beads, metallic beads, colloidal particles, fluorescent dyes, enzymes, biotin, digoxigenin, haptens, and the like. A “labeled nucleic acid or oligonucleotide probe” is generally one that is bound, either covalently, through a linker or a chemical bond, or noncovalently, through ionic bonds, van der Waals forces, electrostatic attractions, hydrophobic interactions, or hydrogen bonds, to a label such that the presence of the nucleic acid or probe can be detected by detecting the presence of the label bound to the nucleic acid or probe.

The terms “polymerase chain reaction,” or “PCR,” as used herein generally refers to a procedure wherein small amounts of a nucleic acid, RNA and/or DNA, are amplified as described, for example, in U.S. Pat. No. 4,683,195 to Mullis. Generally, sequence information from the ends of the region of interest or beyond needs to be available, such that oligonucleotide primers can be designed; these primers will be identical or similar in sequence to opposite strands of the template to be amplified. The 5′ terminal nucleotides of the two primers may coincide with the ends of the amplified material. PCR can be used to amplify specific RNA sequences, specific DNA sequences from total genomic DNA, and cDNA transcribed from total cellular RNA, bacteriophage or plasmid sequences, etc. See generally Mullis et al., Cold Spring Harbor Symp. Quant. Biol., 51: 263 (1987); Erlich, ed., PCR Technology, (Stockton Press, N Y, 1989).

The term “cycle number” or “CT” when used herein in reference to PCR methods, refers to the PCR cycle number at which the fluorescence level passes a given set threshold level.

In other embodiments of the various methods provided herein, the method comprises using immunohistochemistry to determine the level of the biomarker. In some embodiments, the method comprises using dual staining immunohistochemistry to determine the level of the biomarker.

The reference level can be determined by a plurality of methods. In some embodiments, the reference level is one that a treatment decision is made based on whether a subject having or suspected of having a disease, such as a cancer (e.g., DLBCL, MM, MDS or AML) has the level of the biomarker above the reference level. Subjects who have a level of the biomarker higher than the reference level have a different probability of responsiveness to the treatment than subjects who have a level of the biomarker lower than the reference level. In certain embodiments, the reference level is measured simultaneously with the biological sample from the subject. In some embodiments, the reference level is predetermined.

In some embodiments, the reference level is determined from a sample from the same subject that contains no disease cells, such as a cancer (e.g., DLBCL, MM, MDS or AML) cells. In other embodiments, the reference level is determined from a sample from a group of subjects that contains no disease cells, such as a cancer (e.g., DLBCL, MM, MDS or AML) cells. In yet other embodiments, the reference level is determined from a sample from a group of subjects who do not have the disease, such as a cancer (e.g., DLBCL, MM, MDS or AML). An increased level or a decreased level of the biomarker correlates positively with increased responsiveness of the subject to a treatment by a treatment compound (e.g., thalidomide, lenalidomide, pomalidomide, Compound A, or Compound B, or a stereoisomer thereof, or a pharmaceutically acceptable salt, solvate, hydrate, co-crystal, clathrate, or a polymorph thereof).

In some embodiments, the control sample is a sample containing no disease cells, such as a cancer (e.g., DLBCL, MM, MDS or AML) cells from the same subject. In other embodiments, the control sample is a sample containing no disease cells, such as a cancer (e.g., DLBCL, MM, MDS or AML) cells from a group of subjects. In yet other embodiments, the control sample is a sample from a subject having no disease, such as a cancer (e.g., DLBCL, MM, MDS or AML). In yet other embodiments, the control sample is a sample from a group of subjects having no disease, such as a cancer (e.g., DLBCL, MM, MDS or AML). An increased or a decreased level of the one or more biomarkers as compared with the level of the control sample correlates positively with increased responsiveness of the subject to a treatment by a treatment compound.

In some embodiments, the reference is prepared by using a second tumor cell not treated with the compound. In other embodiments, the reference is prepared by using a second sample obtained from the subject prior to administration of the treatment compound to the patient; and wherein the second sample is from the same source as the sample. In yet other embodiments, the reference is prepared by using a second sample obtained from a healthy subject not having a disease, such as a cancer (e.g., DLBCL, MM, MDS or AML); and wherein the second sample is from the same source as the sample.

In certain embodiments, the change in the level of a biomarker may be evaluated by a statistical hypothesis test, for example, against a null hypothesis of no difference between two levels (e.g., sample vs. reference) at a pre-determined level of significance. For example, the p value might, in certain embodiments, be less than 0.01, less than 0.0.001, less than 10⁻⁴, less than 10⁻⁵, less than 10⁻⁶, less than 10⁻⁷, less than 10⁻⁸ and so forth. Such exemplary methods are provided in Section 6, infra.

In some embodiments, the protein level of biomarker is measured. For example, in some embodiments, the method provided herein comprises contacting proteins within the sample with a first antibody that immunospecifically binds to biomarker protein. In some embodiments, the method provided herein further includes (i) contacting the proteins bound to the first antibody with a second antibody with a detectable label, wherein the second antibody immunospecifically binds to biomarker, and wherein the second antibody immunospecifically binds to a different epitope on biomarker protein than the first antibody; (ii) detecting the presence of second antibody bound to the proteins; and (iii) determining the amount of biomarker protein based on the amount of detectable label in the second antibody. In other embodiments, the method provided herein further comprises (i) contacting the proteins bound to the first antibody with a second antibody with a detectable label, wherein the second antibody immunospecifically binds to the first antibody; (ii) detecting the presence of second antibody bound to the proteins; and (iii) determining the amount of biomarker protein based on the amount of detectable label in the second antibody.

Therapeutically effective amounts of the treatment compounds depend on the recipient of the treatment, the disorder being treated and the severity thereof, the composition containing the treatment compound, the time of administration, the route of administration, the duration of treatment, the compound potency, its rate of clearance and whether or not another drug is co-administered. In some embodiments, the amount of a treatment compound provided herein used to make a composition to be administered daily to a subject in a single dose or in divided doses is from about 0.03 to about 200 mg/kg body weight. Single dose compositions contain these amounts or a combination of submultiples thereof. In some embodiments, 1 mg/day to 100 mg/day treatment compounds are administered to the subject having DLBCL or MM. Exemplary daily dose includes 1, 5, 10, 15, 20, 25, 30, 35, 40, 50, 60, 70, 80, 90 or 100 mg. In some embodiments, treatment compounds are administered for 1 to 40 days.

The methods provided herein are also based, in part, on the finding that CRBN is associated with the anti-proliferative activities of certain drugs, such as the compounds provided herein. CRBN or a CAP (e.g., Ikaros, Aiolos, IFN, an IFN pathway protein, CSNK1A1, ZFP91 or a combination thereof) can be utilized as a biomarker(s) to indicate the effectiveness or progress of a disease treatment with a compound provided herein. Thus, in certain embodiments, the methods provided herein are useful for characterizing a disease or disorder (e.g., a cancer, such as DLBCL, MM, MDS or AML) in a subject, prior to, during or after the subject receiving a treatment of an immunomodulatory compound (e.g., a compound provided in Section 5.7 below).

Without being bound to a particular theory, CRBN binding may contribute to or even be required for anti-proliferative or other activities of certain compounds, such as the compounds provided herein. In certain embodiments, the compounds provided herein target CRBN or one or more CAPs. In one embodiment, the compounds provided herein bind directly to CRBN-DDB1 and/or the CRBN E3 ubiquitin-ligase complex. Mutations in CRBN could be associated with resistance to the compounds provided herein.

For example, the levels of Aiolos and Ikaros were significantly lower in the lenalidomide-resistant cells lines WSU-DLCL2 and TMD8 and the 3-(5-amino-2-methyl-4-oxo-4H-quinazolin-3-yl)-piperidine-2,6-dione cell line WSU-DLCL2 compared to the matched parental lines. Thus, in certain embodiments, the sensitivity of a cancer (e.g., DLBCL, MM, MDS or AML) or a patient having a cancer a cancer (e.g., DLBCL, MM, MDS or AML), to therapy with a compound provided herein is related to Aiolos and/or Ikaros levels.

IRF4 inhibition by lenalidomide caused downregulation of B cell receptor (BCR)-dependent NF-κB activation. While IRF4-specific siRNA mimicked effects of lenalidomide reducing NF-κB activation, IRF4 overexpression enhanced NF-κB activation and conferred resistance to lenalidomide. Furthermore, lenalidomide-induced IRF4 downregulation required the expression of CRBN. Without being bound to a particular theory, these data show that lenalidomide may have direct antitumor activity against DLBCL cells, preferentially ABC-DLBCL cells, by blocking IRF4 expression and the BCR-NF-κB signaling pathway in a CRBN-dependent manner.

It has been proposed that CRBN protein functions as a substrate receptor for Cul4-E3-ligase complexes through its interaction with DDB1. In H929 cells, compounds provided herein decrease total K48-linked polyubiquitination but not K-63-linked ubiquitination after 30 minutes treatment. At present, nearly two dozen proteins are reported to be degraded by a Cul4-DDB1 ligase2. Several studies have shown Cul4/DDB1-dependent ubiquitination of core histones, DNA repair proteins, cell cycle regulators and key signaling pathways molecules. mTORC1 signaling requires proteasomal function and the involvement of CUL4-DDB1 ubiquitin E3 ligase. Using CST Ubiscan technology, 162 unique ubiquitin-peptides were identified which were significantly modulated by the compounds provided herein after short treatments (1-4 h). The corresponding proteins participate in nucleosome and chromatin function, protein-DNA assembly and histone H2A. The relevance of this early modification in the mode of action of compounds provided herein, and the relationship with CRBN and CUL4/DDB1 activities are under investigation.

The embodiments reflected in examples provided in Section 6 below show, among other things: (i) Aiolos and Ikaros are substrates of consequence for lenalidomide and Compound A in DLBCL, and Aiolos and Ikaros are degraded in a lenalidomide and Compound A dependent mechanism in both ABC and GCB DLBCL; (ii) Aiolos is a driver of proliferation in DLBCL, and Aiolos shRNA results in decreased c-myc levels and reduced proliferative capacity; (iii) CRBN, Aiolos and Ikaros are shown to be useful as predictive biomarkers of response in DLBCL, and a dynamic range or expression of CRBN, Aiolos and Ikaros can be useful as a patient stratification strategy for lenalidomide and/or Compound A clinical trials; (iv) mechanism(s) of resistance for lenalidomide and Compound A in DLBCL, and cell lines resistant to lenalidomide and Compound A downregulate levels of Aiolos, Ikaros and c-myc, potentially as a resistance mechanism; (v) differentiation of lenalidomide and Compound A mechanism of Action in DLBCL, and ABC DLBCL cell lines are sensitive to lenalidomide and Compound A, while GCB cell lines are less sensitive to lenalidomide; (vi) IFN and CSNK1A1 are substrates of consequence for lenalidomide and/or Compound A in DLBCL, and Compound A induces IFN response in both ABC and GCB DLBCL; (vii) the level of ZFP91 decreases in response to lenalidomide, pomalidomide, Compound A, thalidomide, or Compound B treatment; and (viii) the level of ZFP91 decreases in response to treatment using compounds provided herein through a CRBN-dependent pathway.

In certain embodiments, the methods provided herein are useful for assessing the clinical sensitivity and patient response to treatment an immunomodulatory compound (e.g., a compound provided in Section 5.7 below). In one embodiment, the immunomodulatory compound provided herein regulate (e.g., down-regulate or decrease) CRBN or one or more CAPs (e.g., Ikaros, Aiolos, ZFP91 or a combination thereof). In one embodiment, the compound provided herein regulate (e.g., up-regulate or down-regulate) CRBN or one or more CAPs (e.g., IFN, an IFN pathway protein, CSNK1A1, or a combination thereof). In another embodiment, the immunomodulatory compound provided herein provided herein binds directly to CRBN-DDB1.

5.3. Methods of Detecting and Quantifying CRBN or CRBN-Associated Proteins

In certain embodiments, provided herein are methods of detecting and quantifying the protein level of biomarker, such as CRBN or a CAP, from a biological sample, comprising: (a) contacting the sample with a first antibody that immunospecifically binds to the biomarker; (b) contacting the sample bound to the first antibody with a second antibody with a detectable label, wherein the second antibody immunospecifically binds to the biomarker, and wherein the second antibody immunospecifically binds to a different epitope on the biomarker than the first antibody; (c) detecting the presence of second antibody bound to the sample; and (d) determining the protein level of the biomarker based on the amount of detectable label in the second antibody.

In some embodiments of the various methods provided herein, the method comprises using dual staining immunohistochemistry to determine the level of a biomarker, such as CRBN or a CAP. In a dual staining immunohistochemistry assay, a CAP and another cancer biomarker are simultaneously detected using a first labeled antibody targeting a CAP and a second labeled antibody targeting a cancer biomarker. Such assay can improve the specificity, accuracy and sensitivity for detecting and measuring a CAP. In some embodiments, the cancer biomarker is a DLBCL biomarker. In some embodiments, the cancer biomarker is a MM biomarker. In some embodiments, the cancer biomarker is a MDS biomarker. In some embodiments, the cancer biomarker is an AML biomarker. In some embodiments, the cancer biomarker is CD138. CD138 is a plasma cell and multiple myeloma biomarker. In addition, because the assay can simultaneously detect CD138 and a CAP in the same cell sample, the assay can detect tumor samples (containing CD138 positive cells) that express no or fewer CAPs. Thus, the dual staining immunohistochemistry method provided herein provides, among various advantages, a more sensitive measurement of a change of a CAP in a sample. In some embodiments, the level of a CAP is measured using H-score. The H-score method takes consideration of the tumor cells in the whole specimen that are CD138 positive, either with or without a CAP.

Thus, in some embodiments, the method provided herein comprises (i) contacting proteins within a sample with a first antibody that immunospecifically binds to a CAP, the first antibody being coupled with a first detectable label; (ii) contacting the proteins within the sample with a second antibody that immunospecifically binds to a cancer biomarker, the second antibody being coupled with a second detectable label; (iii) detecting the presence of the first antibody and the second antibody bound to the proteins; and (iv) determining the level of the CAP based on the amount of detectable label in the first antibody, and determining the level of the cancer biomarker based on the amount of detectable label in the second antibody. In some embodiments, the cancer biomarker is a DLBCL biomarker. In some embodiments, the cancer biomarker is a MM biomarker. In some embodiments, the cancer biomarker is a MDS biomarker. In some embodiments, the cancer biomarker is an AML biomarker. In some embodiments, the cancer biomarker is CD138. In some embodiments, H-score is used to determine the level of the CAP. In some embodiments, H-score is used to determine the level of the CAP when the level of the cancer biomarker is higher than a reference level.

In certain embodiments, provided herein are methods of detecting and quantifying the RNA (e.g., mRNA) level of a biomarker, such as CRBN or a CAP, from a biological sample, comprising: (a) obtaining RNA from the sample; (b) contacting the RNA with a primer comprising a sequence specifically binding to a sequence in the RNA to generate a first DNA molecule having a sequence complementary to said RNA; (c) amplifying the DNA corresponding to a segment of a gene encoding the biomarker; and (d) determining the RNA level of the biomarker based on the amount of the amplified DNA.

In some embodiments, the biomarker(s) are evaluated in combination with other biomarker(s) provided herein, such as Ikaros, Aiolos, IFN, an IFN pathway protein, CSNK1A1 and/or ZFP91.

In certain embodiments of the various methods provided herein, the two or more of the steps are performed sequentially. In other embodiments of the methods provided herein, two or more of steps are performed in parallel (e.g., at the same time).

Exemplary assays provided herein for the methods of detecting and quantifying the protein level of a biomarker, such as CRBN or a CAP (e.g., Ikaros, Aiolos, IFN, an IFN pathway protein, CSNK1A1, ZFP91, or a combination thereof) are immunoassays, such as western blot analysis, and an enzyme-linked immunosorbent assay (ELISA) (e.g., a sandwich ELISA). An exemplary assay provided herein for the methods of detecting and quantifying the RNA level of a biomarker, such as CRBN or a CAP (e.g., Ikaros, Aiolos, IFN, an IFN pathway protein, CSNK1A1, ZFP91, or a combination thereof) is reverse transcription polymerase chain reaction (RT-PCR), e.g., quantitative PCR or qPCR.

Such cells can include any type of cells, e.g., stem cells, blood cells (e.g., peripheral blood mononuclear cells), lymphocytes, B cells, T cells, monocytes, granulocytes, immune cells, or tumor or cancer cells. The tumor or cancer cells or a tumor tissue, such as a tumor biopsy or a tumor explants.

The number of cells, such as cancer (e.g., DLBCL, MM, MDS, or AML) cells used in the methods can range from a single cell to about 10⁹ cells. B cells (B lymphocytes) include, for example, plasma B cells, memory B cells, B1 cells, B2 cells, marginal-zone B cells, and follicular B cells. B cells can express immunoglobulins (antibodies, B cell receptor). In one embodiment, the cells used in the methods provided herein are Karpas 422, TMD8, WSU-DLCL2, OCI-LY10, Karpas 1106P, HT, SUDHL-10, Riva, OCI-LY19, SUDHL-4, SUDHL-6, OCI-LY3, Farage, U266, DF15, or RPMI, e.g., as detected by flow cytometry.

Specific cell populations can be obtained using a combination of commercially available antibodies (e.g., Quest Diagnostic (San Juan Capistrano, Calif.); Dako (Denmark)).

The cells in the methods provided herein can be obtained from a cell line. In certain embodiments, the cell line is lenalidomide-resistant WSU-DLCL2 or TMD8 cell line. In certain embodiments, the cell line is a DLBCL cell line. In certain embodiments, the cell line is a ABC-DLBCL (activated B cell-like DLBCL) cell line, for example, TMD8, OCI-LY10, Riva, or OCI-LY3 cell line.

In some embodiments, the cell line is a HNT-34 cell line.

It is understood that results provided in the examples herein can, in certain embodiments, be extrapolated to cancer cells from wider patient populations.

In certain embodiments, the sample used in the methods provided herein is from a diseased tissue, e.g., from an individual having cancer (e.g., DLBCL, MM, MDS or AML). In certain embodiments, the methods provided herein are useful for detecting gene rearrangement in cells from a healthy individual. In certain embodiments, the number of cells used in the methods provided herein can range from a single cell to about 10⁹ cells. In some embodiments, the number of cells used in the methods provided herein is about 1×10⁴, 5×10⁴, 1×10⁵, 5×10⁵, 1×10⁶, 5×10⁶, 1×10⁷, 5×10⁷, 1×10⁸, or 5×10⁸.

The number and type of cells collected from a subject can be monitored, for example, by measuring changes in morphology and cell surface markers using standard cell detection techniques such as flow cytometry, cell sorting, immunocytochemistry (e.g., staining with tissue specific or cell-marker specific antibodies) fluorescence activated cell sorting (FACS), magnetic activated cell sorting (MACS), by examination of the morphology of cells using light or confocal microscopy, and/or by measuring changes in gene expression using techniques well known in the art, such as PCR and gene expression profiling. These techniques can be used, too, to identify cells that are positive for one or more particular markers. Fluorescence activated cell sorting (FACS) is a well-known method for separating particles, including cells, based on the fluorescent properties of the particles (Kamarch, 1987, Methods Enzymol, 151:150-165). Laser excitation of fluorescent moieties in the individual particles results in a small electrical charge allowing electromagnetic separation of positive and negative particles from a mixture. In one embodiment, cell surface marker-specific antibodies or ligands are labeled with distinct fluorescent labels. Cells are processed through the cell sorter, allowing separation of cells based on their ability to bind to the antibodies used. FACS sorted particles may be directly deposited into individual wells of 96-well or 384-well plates to facilitate separation and cloning.

In certain embodiments, subsets of cells are used in the methods provided herein. Methods to sort and isolate specific populations of cells are well-known in the art and can be based on cell size, morphology, or intracellular or extracellular markers. Such methods include, but are not limited to, flow cytometry, flow sorting, FACS, bead based separation such as magnetic cell sorting, size-based separation (e.g., a sieve, an array of obstacles, or a filter), sorting in a microfluidics device, antibody-based separation, sedimentation, affinity adsorption, affinity extraction, density gradient centrifugation, laser capture microdissection, etc.

In one embodiment, the RNA (e.g., mRNA) or protein is purified from the tumor and the presence or absence of a biomarker is measured by gene or protein expression analysis. In certain embodiments, the presence or absence of a biomarker is measured by quantitative real-time PCR (QRT-PCR), microarray, flow cytometry or immunofluorescence. In other embodiments, the presence or absence of a biomarker is measured by enzyme-linked immunosorbent assay-based methodologies (ELISA) or other similar methods known in the art.

5.5. Methods of Detecting mRNA Levels in a Sample

Several methods of detecting or quantitating mRNA levels are known in the art. Exemplary methods include but are not limited to northern blots, ribonuclease protection assays, PCR-based methods, and the like. The mRNA sequence (e.g., the mRNA of a biomarker, such as CRBN or a CAP, or a fragment thereof), can be used to prepare a probe that is at least partially complementary. The probe can then be used to detect the mRNA sequence in a sample, using any suitable assay, such as PCR-based methods, Northern blotting, a dipstick assay, and the like.

In other embodiments, a nucleic acid assay for testing for immunomodulatory activity in a biological sample can be prepared. An assay typically contains a solid support and at least one nucleic acid contacting the support, where the nucleic acid corresponds to at least a portion of an mRNA that has altered expression during an immunomodulatory treatment in a patient, such as the mRNA of a biomarker (e.g., CRBN or a CAP). The assay can also have a means for detecting the altered expression of the mRNA in the sample.

The assay method can be varied depending on the type of mRNA information desired. Exemplary methods include but are not limited to Northern blots and PCR-based methods (e.g., qRT-PCR). Methods such as qRT-PCR can also accurately quantitate the amount of the mRNA in a sample.

Any suitable assay platform can be used to determine the presence of the mRNA in a sample. For example, an assay may be in the form of a dipstick, a membrane, a chip, a disk, a test strip, a filter, a microsphere, a slide, a multiwell plate, or an optical fiber. An assay system may have a solid support on which a nucleic acid corresponding to the mRNA is attached. The solid support may comprise, for example, a plastic, silicon, a metal, a resin, glass, a membrane, a particle, a precipitate, a gel, a polymer, a sheet, a sphere, a polysaccharide, a capillary, a film a plate, or a slide. The assay components can be prepared and packaged together as a kit for detecting an mRNA.

The nucleic acid can be labeled, if desired, to make a population of labeled mRNAs. In general, a sample can be labeled using methods that are well known in the art (e.g., using DNA ligase, terminal transferase, or by labeling the RNA backbone, etc.; see, e.g., Ausubel, et al., Short Protocols in Molecular Biology, 3rd ed., Wiley & Sons 1995 and Sambrook et al., Molecular Cloning: A Laboratory Manual, Third Edition, 2001 Cold Spring Harbor, N.Y.). In some embodiments, the sample is labeled with fluorescent label. Exemplary fluorescent dyes include but are not limited to xanthene dyes, fluorescein dyes, rhodamine dyes, fluorescein isothiocyanate (FITC), 6 carboxyfluorescein (FAM), 6 carboxy-2′,4′,7′,4,7-hexachlorofluorescein (HEX), 6 carboxy 4′, 5′ dichloro 2′, 7′ dimethoxyfluorescein (JOE or J), N,N,N′,N′ tetramethyl 6 carboxyrhodamine (TAMRA or T), 6 carboxy X rhodamine (ROX or R), 5 carboxyrhodamine 6G (R6G5 or G5), 6 carboxyrhodamine 6G (R6G6 or G6), and rhodamine 110; cyanine dyes, e.g. Cy3, Cy5 and Cy7 dyes; Alexa dyes, e.g. Alexa-fluor-555; coumarin, Diethylaminocoumarin, umbelliferone; benzimide dyes, e.g. Hoechst 33258; phenanthridine dyes, e.g. Texas Red; ethidium dyes; acridine dyes; carbazole dyes; phenoxazine dyes; porphyrin dyes; polymethine dyes, BODIPY dyes, quinoline dyes, Pyrene, Fluorescein Chlorotriazinyl, R110, Eosin, JOE, R6G, Tetramethylrhodamine, Lissamine, ROX, Napthofluorescein, and the like.

In one embodiment, the mRNA is Ikaros mRNA. In another embodiment, the mRNA is Aiolos mRNA. In another embodiment, the mRNA is IFITM3 mRNA. In another embodiment, the mRNA is CSNK1A1 mRNA. In other embodiments, the mRNA is IFIT3 mRNA. In one embodiment, the mRNA is DDX58 mRNA. In one embodiment, the mRNA is XAF1 mRNA. In one embodiment, the mRNA is IFIH1 mRNA. In one embodiment, the mRNA is IFI27 mRNA. In one embodiment, the mRNA is IFIT1 mRNA. In one embodiment, the mRNA is ISG 15 mRNA. In other embodiments, the mRNA is an IRF mRNA. In one embodiment, the mRNA is ZFP91 mRNA. The nucleic acids may be present in specific, addressable locations on a solid support; each corresponding to at least a portion of mRNA sequences that are differentially expressed upon treatment of an immunomodulatory compound in a cell or a patient.

A typical mRNA assay method can contain the steps of 1) obtaining surface-bound subject probes; 2) hybridization of a population of mRNAs to the surface-bound probes under conditions sufficient to provide for specific binding (3) post-hybridization washes to remove nucleic acids not bound in the hybridization; and (4) detection of the hybridized mRNAs. The reagents used in each of these steps and their conditions for use may vary depending on the particular application.

Hybridization can be carried out under suitable hybridization conditions, which may vary in stringency as desired. Typical conditions are sufficient to produce probe/target complexes on a solid surface between complementary binding members, i.e., between surface-bound subject probes and complementary mRNAs in a sample. In certain embodiments, stringent hybridization conditions may be employed.

Hybridization is typically performed under stringent hybridization conditions. Standard hybridization techniques (e.g. under conditions sufficient to provide for specific binding of target mRNAs in the sample to the probes) are described in Kallioniemi et al., Science 258:818-821 (1992) and WO 93/18186. Several guides to general techniques are available, e.g., Tijssen, Hybridization with Nucleic Acid Probes, Parts I and II (Elsevier, Amsterdam 1993). For descriptions of techniques suitable for in situ hybridizations, see Gall et al. Meth. Enzymol., 21:470-480 (1981); and Angerer et al. in Genetic Engineering: Principles and Methods (Setlow and Hollaender, Eds.) Vol 7, pgs 43-65 (Plenum Press, New York 1985). Selection of appropriate conditions, including temperature, salt concentration, polynucleotide concentration, hybridization time, stringency of washing conditions, and the like will depend on experimental design, including source of sample, identity of capture agents, degree of complementarity expected, etc., and may be determined as a matter of routine experimentation for those of ordinary skill in the art.

Those of ordinary skill will readily recognize that alternative but comparable hybridization and wash conditions can be utilized to provide conditions of similar stringency.

After the mRNA hybridization procedure, the surface bound polynucleotides are typically washed to remove unbound nucleic acids. Washing may be performed using any convenient washing protocol, where the washing conditions are typically stringent, as described above. The hybridization of the target mRNAs to the probes is then detected using standard techniques.

Other methods, such as PCR-based methods, can also be used to follow the expression of CRBN or CRB-associated proteins. Examples of PCR methods can be found in the literature. Examples of PCR assays can be found in U.S. Pat. No. 6,927,024, which is incorporated by reference herein in its entirety. Examples of RT-PCR methods can be found in U.S. Pat. No. 7,122,799, which is incorporated by reference herein in its entirety. A method of fluorescent in situ PCR is described in U.S. Pat. No. 7,186,507, which is incorporated by reference herein in its entirety.

In some embodiments, Real-Time Reverse Transcription-PCR (qRT-PCR) can be used for both the detection and quantification of RNA targets (Bustin, et al., 2005, Clin. Sci., 109:365-379). Quantitative results obtained by qRT-PCR are generally more informative than qualitative data. Thus, in some embodiments, qRT-PCR-based assays can be useful to measure mRNA levels during cell-based assays. The qRT-PCR method is also useful to monitor patient therapy. Examples of qRT-PCR-based methods can be found, for example, in U.S. Pat. No. 7,101,663, which is incorporated by reference herein in its entirety.

In contrast to regular reverse transcriptase-PCR and analysis by agarose gels, real-time PCR gives quantitative results. An additional advantage of real-time PCR is the relative ease and convenience of use. Instruments for real-time PCR, such as the Applied Biosystems 7500, are available commercially, as are the reagents, such as TaqMan Sequence Detection chemistry. For example, TaqMan Gene Expression Assays can be used, following the manufacturer's instructions. These kits are pre-formulated gene expression assays for rapid, reliable detection and quantification of human, mouse and rat mRNA transcripts. An exemplary PCR program, for example, is 50° C. for 2 minutes, 95° C. for 10 minutes, 40 cycles of 95° C. for 15 seconds, then 60° C. for 1 minute.

To determine the cycle number at which the fluorescence signal associated with a particular amplicon accumulation crosses the threshold (referred to as the CT), the data can be analyzed, for example, using a 7500 Real-Time PCR System Sequence Detection software v1.3 using the comparative CT relative quantification calculation method. Using this method, the output is expressed as a fold-change of expression levels. In some embodiments, the threshold level can be selected to be automatically determined by the software. In some embodiments, the threshold level is set to be above the baseline but sufficiently low to be within the exponential growth region of an amplification curve.

Techniques known to one skilled in the art may be used to measure the amount of an RNA transcript(s). In some embodiments, the amount of one, two, three, four, five or more RNA transcripts is measured using deep sequencing, such as ILLUMINA® RNASeq, ILLUMINA® next generation sequencing (NGS), ION TORRENT™ RNA next generation sequencing, 454™ pyrosequencing, or Sequencing by Oligo Ligation Detection (SOLID™). In other embodiments, the amount of multiple RNA transcripts is measured using a microarray and/or gene chip, such as described in Section 6, infra. In certain embodiments, the amount of one, two, three or more RNA transcripts is determined by RT-PCR. In other embodiments, the amount of one, two, three or more RNA transcripts is measured by RT-qPCR. Techniques for conducting these assays are known to one skilled in the art. Other examples of assays to measure RNA transcripts are described elsewhere herein.

In some embodiments, a statistical analysis or other analysis is performed on data from the assay utilized to measure an RNA transcript or protein. In certain specific embodiments, p value of those RNA transcripts or proteins differentially expressed is 0.1, 0.5, 0.4, 0.3, 0.2, 0.01, 0.05, 0.001, 0.005, or 0.0001. In specific embodiments, a false discovery rate (FDR) of 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1% or less is selected.

5.6. Methods of Detecting Polypeptide or Protein Levels in a Sample

Several protein detection and quantitation methods can be used to measure the level of a biomarker, such as CRBN or a CAP. Any suitable protein quantitation method can be used. In some embodiments, antibody-based methods are used. Exemplary methods that can be used include but are not limited to immunoblotting (Western blot), enzyme-linked immunosorbent assay (ELISA), immunohistochemistry, flow cytometry, cytometric bead array, mass spectroscopy, and the like. In certain embodiments, a biomarker protein is detected using mass spectroscopy. Exemplary mass spectroscopy methods that can be used are provided in Section 6, infra. Several types of ELISA are commonly used, including direct ELISA, indirect ELISA, and sandwich ELISA. In certain embodiments, the biomarker is a CAP. In one embodiment, the CAP is Ikaros. In another embodiment, the CAP is Aiolos. In another embodiment, the CAP is CSNK1A1. In other embodiments, the CAP is IFN-induced protein with IFIT3, DDX58, XAF1, IFIH1, OAS3, IFI27, IFIT1, or ISG15, or a combination thereof. In other embodiments, the CAP is an IRF. In one embodiment, the IRF is selected from a group consisting of IRF1, IRF3, IRF4, IRF7, and IRF9. In other embodiments, the CAP is TBK1 or TBK1-PO4. In another embodiment, the CAP is CSNK1A1. In another embodiment, the CAP is ZFP91.

The organic layer was washed with water (30 mL), brine (30 mL), dried over MgSO₄ and concentrated. To the resulting solid was added EtOAc (10 mL) followed by hexane (10 mL) under stirring. The suspension was filtered to give 3-[4-(4-morpholin-4-ylmethyl-benzyloxy)-1-oxo-1,3-dihydro-isoindol-2-yl]-piperidine-2,6-dione as white solid (1.5 g, 73% yield). HPLC: Waters Symmetry C₁₈, 5 μm, 3.9×150 mm, 1 mL/min, 240 nm, gradient to 95/5 acetonitrile/0.1% H₃PO₄ in 5 min,: t_(R)=4.78 min (97.5%); mp: 210-212° C.; ¹H NMR (DMSO-d₆) δ 1.86-2.09 (m, 1H, CHH), 2.29-2.38 (m, 4H, CH₂, CH₂), 2.44 (dd, J=4.3, 13.0 Hz, 1H, CHH), 2.53-2.64 (m, 1H, CHH), 2.82-2.99 (m, 1H, CHH), 3.46 (s, 2H, CH₂), 3.52-3.61 (m, 4H, CH₂, CH₂), 4.18-4.51 (m, 2H, CH₂), 5.11 (dd, J=5.0, 13.3 Hz, 1H, NCH), 5.22 (s, 2H, CH₂), 7.27-7.38 (m, 5H, Ar), 7.40-7.53 (m, 3H, Ar), 10.98 (s, 1H, NH) ¹³C NMR (DMSO-d₆) δ 22.36, 31.21, 45.09, 51.58, 53.14, 62.10, 66.17, 69.41, 114.97, 115.23, 127.64, 128.99, 129.81, 129.95, 133.31, 135.29, 137.68, 153.50, 168.01, 170.98, 172.83; LCMS: 465; Anal Calcd for C₂₅H₂₇N₃O₅+0.86 H₂O: C, 64.58; H, 6.23; N, 9.04. Found: C, 64.77; H, 6.24; N, 8.88.

Procedure 2

Step 1: To a 2-L round bottom flask, were charged methyl 5-amino-4-(4-hydroxy-1-oxoisoindolin-2-yl)-5-oxopentanoate (30 g, 103 mmol), 1,4-bis(bromomethyl)benzene (81 g, 308 mmol) and potassium carbonate (14.19 g, 103 mmol) and acetonitrile (1.2 L). The mixture was stirred at room temperature for 10 minutes and heated to 50° C. for 12 hours. The reaction mixture was allowed to cool to room temperature. The mixture was filtered and the filtrate was concentrated on rota-vap. The resulting solid was dissolved in CH₂Cl₂ and loaded on 2 silica gel columns (330 g each) and eluted using CH₂Cl₂/MeOH to give 4-[4-(4-bromomethyl-benzyloxy)-1-oxo-1,3-dihydro-isoindol-2-yl]-4-carbamoyl-butyric acid methyl ester as white solid (40 g, 82% yield): ¹H NMR (DMSO-d₆) δ 1.98-2.13 (m, 1H, CHH), 2.14-2.23 (m, 1H, CHH), 2.23-2.32 (m, 2H, CHH, CHH), 3.50 (s, 3H, CH₃), 4.34-4.63 (m, 2H, CH₂), 4.67-4.80 (m, 3H, CH₂, NCH), 5.25 (s, 4H, CH₂), 7.19 (s, 1H, NHH), 7.24-7.34 (m, 2H, Ar), 7.41-7.54 (m, 5H, Ar), 7.58 (br. s., 1H, NHH).

Step 2: To the CH₂Cl₂ solution of methyl 5-amino-4-(4-(4-(bromomethyl)benzyloxy)-1-oxoisoindolin-2-yl)-5-oxopentanoate (36.5 g, 77 mmol), was added morpholine (14.72 ml, 169 mmol) at room temperature. The mixture was stirred at room temperature for 1 hour. The resulting suspension was filtered, and the filtrate was concentrated on rota-vap. The resulting oil was dissolved in 350 mL of EtOAc and washed with water (50 mL×3). The organic layer was concentrated on rota-vap to give 4-carbamoyl-4-[4-(4-morpholin-4-ylmethyl-benzyloxy)-1-oxo-1,3-dihydro-isoindol-2-yl]-butyric acid methyl ester as a foamy solid (39 g, 100% yield): ¹H NMR (DMSO-d₆) δ 2.00-2.12 (m, 1H, CHH), 2.14-2.22 (m, 1H, CHH), 2.22-2.29 (m, 2H, CHH, CHH), 2.30-2.39 (m, 4H, CH₂, CH₂), 3.46 (s, 2H, CH₂), 3.50 (s, 3H, CH₃), 3.53-3.63 (m, 4H, CH₂, CH₂), 4.28-4.59 (m, 2H, CH₂), 4.73 (dd, J=4.7, 10.2 Hz, 1H, NCH), 5.22 (s, 2H, CH₂), 7.14-7.23 (m, 1H, NHH), 7.26-7.39 (m, 4H, Ar), 7.41-7.51 (m, 3H, Ar), 7.58 (s, 1H, NHH).

Step 3: To the THF solution of methyl 5-amino-4-(4-(4-(morpholinomethyl)benzyloxy)-1-oxoisoindolin-2-yl)-5-oxopentanoate (40 g, 83 mmol), was added potassium 2-methylpropan-2-olate (9.80 g, 87 mmol) portion wise at 0° C. The mixture was stirred at this temperature for 30 minutes. To the reaction mixture, was added 45 mL of 1N HCl solution, followed by 200 mL of saturated NaHCO₃ solution. The mixture was diluted with 500 mL of EtOAc at 0° C., stirred for 5 minutes and separated. The organic layer was washed with water (50 mL×3) and brine (100 mL), and concentrated on rota-vap to give a white solid, which was stirred in diethyl ether (300 mL) to give a suspension. The suspension was filtered to give 3-[4-(4-morpholin-4-ylmethyl-benzyloxy)-1-oxo-1,3-dihydro-isoindol-2-yl]-piperidine-2,6-dione as white solid (28.5 g, 72% yield): HPLC: Waters Symmetry C₁₈, 5 μm, 3.9×150 mm, 1 mL/min, 240 nm, gradient to 95/5 acetonitrile/0.1% H₃PO₄ in 5 min,: t_(R)=4.78 min (98.5%); mp: 209-211° C.; ¹H NMR (DMSO-d₆) δ 1.86-2.09 (m, 1H, CHH), 2.29-2.38 (m, 4H, CH₂, CH₂), 2.44 (dd, J=4.3, 13.0 Hz, 1H, CHH), 2.53-2.64 (m, 1H, CHH), 2.82-2.99 (m, 1H, CHH), 3.46 (s, 2H, CH₂), 3.52-3.61 (m, 4H, CH₂, CH₂), 4.18-4.51 (m, 2H, CH₂), 5.11 (dd, J=5.0, 13.3 Hz, 1H, NCH), 5.22 (s, 2H, CH₂), 7.27-7.38 (m, 5H, Ar), 7.40-7.53 (m, 3H, Ar), 10.98 (s, 1H, NH); ¹³C NMR (DMSO-d₆) δ 22.36, 31.21, 45.09, 51.58, 53.14, 62.10, 66.17, 69.41, 114.97, 115.23, 127.64, 128.99, 129.81, 129.95, 133.31, 135.29, 137.68, 153.50, 168.01, 170.98, 172.83; LCMS: 465; Anal Calcd for C₂₅H₂₇N₃O₅+0.86 H₂O: C, 64.63; H, 6.22; N, 9.04. Found: C, 64.39; H, 6.11; N, 8.89; H₂O, 3.24.

6.4 Cell Culture and Generation of Stable Cell Lines

Cell Culture of DLBCL Cell Lines

Diffuse Large B-Cell Lymphoma (OCI-LY10, OCI-LY3, SUDHL-10, WSU-DLCL2, SUDHL-6, KARPAS-422, TMD8, HT, RIVA, KARPAS-1106P, OCI-LY19 and SUDHL-4) cultured in RPMI-1640 containing 10% fetal bovine serum and 1% Penicillin/Streptomycin.

Generation of Compound-Resistant Cell Lines

Generation of WSU-DLCL2 and TMD8 cells resistant to either Lenalidomide or Compound A was achieved through chronic exposure of compound in an escalating manner.

Gene Silencing with shRNA

WSU-DLCL2, and OCI-LY10 cells were transduced with lentivirus encoding shRNA targeting Aiolos and c-myc. 24 hours post-transduction, cells were cultured with 1 μg/ml of puromycin for stable cell selection.

6.5 Western Blotting

Immunoblots were probed with antibodies recognizing: Aiolos, Ikaros, Cereblon, IRF4, c-myc, CD44, EZH2, EBF1, PU.1, and β-actin. Signals were detected with a LI-COR imager

6.6 Cell Proliferation Assays

2×10e4 cells were plated per well in media containing either DMSO or increasing concentrations of Lenalidomide, Compound A or Compound C. Cells were then cultured for 3 days at 37° C. Tritiated thymidine was applied to the cell culture for the final 6 hours and cells were then harvested onto filter plates. After the plates have dried, scintillation fluid was added to the plates and read on a Top-count reader.

6.7 Current Paradigms in DLBCL

DLBCL is currently subgrouped into three clinical diseases: germinal center B cell (GBC), activated B cell (ABC) and primary mediastinal B cell lymphoma. Historically, patients diagnosed with ABC phenotype have a worse overall prognosis, and lenalidomide has a greater efficacy in ABC phenotype compared to a GCB phenotype. This is shown by greater overall survival in relapsed/refractory ABC patients treated with lenalidomide.

6.8 Aiolos and Ikaros are CRBN Substrates in ABC and GCB

Lenalidomide and Compound A were tested for their activity and effect on various diffuse large B-cell lymphoma (DLBCL) cell lines. The following DLBCL cell lines were evaluated for sensitivity to lenalidomide and Compound A: OCI-Ly10 (ABC), OCI-Ly-3 (ABC), RIVA (ABC), OCI-Ly-19 (GCB), WSU-DLCL2 (GCB), Karpas-1106P (GCB), HT (GCB), SUDHL-10 (GCB), SUDHL-4 (GCB), SUDHL-6 (GCB), Karpas 422 (GCB), and TMD8 (ABC).

The following steps can be performed to harvest cells in preparation for Western Blot analysis. The steps are performed on ice and any centrifugation is performed in a 4° C. refrigerated centrifuge. RIPA lysis buffer (Pierce, cat#89900) is first prepared by adding 10 μL proteinase inhibitors (Pierce, cat#78443) to 1 mL of RIPA buffer. Subsequently, cells are washed once in ice-cold phosphate buffered saline (PBS). The cells are then lysed with 0.25 mL RIPA lysis buffer. The PBMCs are placed on ice for 30 minutes and vortexed every 10 minutes. Lysates are frozen and stored at −80° C. prior to further processing.

Lysates are placed in a QIAshredder® tube (QIAGEN, cat#79656) and spun down 30 sec, top speed (13200 rpm) in an Eppendorf benchtop centrifuge (Model 5415 R). The lysate is then transferred to a 1.5 mL clear Eppendorf tube and spun down 10 min at top speed. The supernatent is collected without disturbing the cell debris pellet. The supernatent is dry ice frozen and stored at −80° C. prior to analysis.

The protein concentration in supernatent is measured using BCA assay and the expected protein yield is about 0.5-5 μg/μL, or 125-1250 μg total. Approximately >10 μg protein per lane is loaded for western blotting (IRF4, IKZF3, etc.) using antibodies against the human proteins.

Membranes are immunblotted with anti-Aiolos (Santa Cruz Biotechnology, Dallas, Tex.), anti-Ikaros (Millipore, Billerica, Mass.) and anti-Actin (Sigma, St. Louis, Mo.; or LI-COR Biosciences, Lincoln, Nebr.) and secondary antibodies (LI-COR Biosciences, Lincoln, Nebr.). The blots are analyzed on Odyssey imager (LI-COR Biosciences, Lincoln, Nebr.).

FIG. 1 shows that Aiolos and Ikaros are CRBN substrates in ABC and GCB DLBCL. DLBCL cells were treated with DMSO, Lenalidomide or Compound A for 1, 6, 12 or 72 hours and then levels of Aiolos, Ikaros, IRF4 or β-actin were assessed.

Karpas 422 (GCB) and TMD8 (ABC) cells were contacted with DMSO (control) or 10 μM lenalidomide or 10 μM Compound A. Aiolos or β-actin (control) levels were evaluated by Western blotting 1 hour, 6 hours or 12 hours later. FIG. 1A shows that lenalidomide and Compound A are biochemically active in both GCB and ABC DLBCL subsets, and Aiolos levels decrease following contact with lenalidomide and Compound A, but not the DMSO control compound.

WSU-DLCL2 (GCB) and OCI-LY10 (ABC) cells were also contacted with DMSO (control) or 10 μM lenalidomide or 10 μM Compound A. Aiolos, Ikaros, IRF4 or β-actin (control) levels were evaluated 1 hour, 6 hours or 12 hours later. FIG. 1B shows that Lenalidomide and Compound A are biochemically active in both GCB and ABC DLBCL subsets, with both Aiolos and Ikaros levels decreasing following contact with lenalidomide and Compound A, but not the DMSO control compound.

WSU-DLCL2 (GCB), Karpas-1106P (GCB), HT (GCB), SUDHL-10 (GCB), RIVA (ABC), OCI-Ly-19 (GCB), SUDHL-4 (GCB), SUDHL-6 (GCB) and OCI-Ly-3 (ABC) cells were also contacted with DMSO (control) or 1 μM or 10 μM lenalidomide, or 1 μM or 10 μM Compound A. Cereblon, Aiolos, Ikaros, IRF4 or β-actin (control) levels were evaluated 72 hours later. FIG. 1C shows that Lenalidomide and Compound A are biochemically active in both GCB and ABC DLBCL subsets, with both Aiolos and Ikaros levels decreasing following contact with lenalidomide and Compound A, but not the DMSO control compound. CRBN levels remained constant. Aiolos and Ikaros are substrates of the CRBN complex in DLBCL; and lenalidomide and Compound A reduce IRF4 levels within 72 hours.

6.9 Aiolos and Ikaros are CRL4^(CRBN) Substrates In Vivo

WSU-DLCL2 xenograft SCID mice can be prepared using methods known in the art. In brief, female CB17 severe combined immunodeficiency (SCID) mice (6-12 weeks old) are obtained from the Charles River Laboratory (Wilmington, Mass.) and maintained in microisolator cages under sterile conditions. A total of 10×10⁶ WSU-DLCL2 DLBCL cells in 100% Matrigel® (Becton Dickinson, San Jose, Calif.) are injected subcutaneously into the right flank of mice. Mice are monitored 2 or 3 times a week for the appearance of tumors. Once the tumors reach an average size of 100-150 mg, mice in each group are treated with either vehicle (e.g., 0.5% carboxymethyl cellulose: 0.25% Tween 80 in deionized H₂O) or a dose of lenalidomide (e.g., 30 mg/kg qd).

WSU-DLCL2 xenograft SCID mice (a human tumor xenograft model) were treated with either vehicle or 30 mg/kg Compound A q.d. Tumor samples were harvested at 1 hour, 6 hours, or 24 hours after the last dose.

Immunohistochemistry was performed using standard methods. For example, immunohistochemistry is performed on the Bond-Max™ automated slide stainer (Leica Microsystems) using the associated Bond™ Polymer Refine Detection Kit. Four micron thick FFPE sections are deparaffinized on the instrument. Antigen retrieval is performed with Epitope Retrieval™ 2 (pH 9.0) for 20 minutes at 100° C. The slides are blocked for endogenous peroxidase activity with Peroxide Block for 5 minutes at room temperature. Sections are then incubated with rabbit polyclonal antibody to Aiolos (Santa Cruz, sc-101982) or Ikaros at a 1/1000 dilution for 15 minutes at room temperature, followed by incubation with HRP labeled Polymer for 8 minutes at room temperature. Enzymatic detection of anti-Aiolos or anti-Ikaros antibody is accomplished with hydrogen peroxide substrate and diaminobenzidine tetrahydrochloride (DAB) chromogen at room temperature for 10 minutes. Slides are counterstained with Hematoxylin for 5 minutes at room temperature.

As shown in FIG. 2, Aiolos and Ikaros are CRL4CRBN substrates in vivo. WSU-DLCL2 xenograft SCID mice were treated with either vehicle or 30 mg/kg Compound A qd. Tumor samples were harvested at indicated time points after last dose. Tissues were then subjected to formalin-fixed, paraffin-embedded (FFPE) immunohistochemistry (IHC) for Aiolos, and Ikaros. Compound A induces Aiolos and Ikaros degradation within 6 hours of treatment in the WSU-DLCL2 xenograft SCID mice.

6.10 Aiolos is a Driver of Lymphoma Proliferation and Regulates c-Myc

WSU-DLCL2 (GCB) and OCI-LY10 (ABC) cells were transfected with negative control siRNA (luciferase) or Aiolos specific siRNA at a concentration of 0, 10 or 100 ng/ml. After 72 hours, Aiolos, IRF4, c-myc and β-actin (control) were measured by Western blot, essentially as described in Section 6.8. Alternatively, after 3 or 5 days, the cells were analyzed for proliferation using a ³H-thymidine incorporation assay.

FIG. 3 shows Aiolos is a driver of lymphoma proliferation and regulates c-Myc. Inducible Aiolos shRNA cell lines were treated with 0-100 ng/ml of doxycycline for 72 hours and Aiolos, c-myc, IRF4 or β-actin protein levels were assessed. As shown in FIG. 3, at least three out of five Aiolos shRNAs (sh1778, sh2982 and sh5472) resulted in a dose-dependent decrease in Aiolos and c-myc protein levels (FIG. 3A), and also showed a corresponding decrease in proliferation in both DLBCL subsets (FIGS. 3B and 3C). Aiolos shRNA results in the significant decrease of c-myc but not IRF4. Proliferation assays indicate that shRNA targeting Aiolos inhibit proliferation of cells at 3 and 5 days post-doxycycline treatment.

6.11 Generation of DLBCL Cell Lines Resistant to Lenalidomide and Compound A

WSU-DLCL2 (GCB) or TMD8 (ABC) were cultured and cell-passaged long-term in lenalidomide or Compound A. Resistance to each compound was assessed using ³H-thymidine incorporation proliferation assays.

FIG. 4 shows the generation of DLBCL cell lines resistant to lenalidomide and Compound A. Cell lines were made resistant to Lenalidomide and Compound A through chronic exposure to both compounds. Proliferation of resistant and parental cells were assessed through tritiated thymidine incorporation assays. As shown in FIG. 4, each of the cell lines demonstrated resistance to lenalidomide (Len-R) or Compound A (CmpA-R), as compared to parental cells, after a 10 day washout period, which indicated that resistance was now an inherent trait in the resistant cells.

6.12 Resistance to Lenalidomide and Compound A Mechanism of Action

FIG. 5 depicts the resistance to lenalidomide and Compound A mechanism of action.

WSU-DLCL2 (GCB) or TMD8 (ABC) were cultured and cell-passaged long-term in lenalidomide or Compound A as described in Section 6.10. Levels of CRBN, Aiolos, Ikaros, IRF4, c-myc, CD44, EZH2, EBF1, PU1 and β-actin (control) were assessed using Western blotting, essentially as described above in Section 6.8.

FIG. 5 shows the resistance to lenalidomide and Compound A mechanism of action. As shown in FIG. 5A, acquired resistance in two DLBCL does not involve downregulation of CRBN levels as is observed in multiple myeloma however, acquired resistance may be achieved through down-regulation of CRBN or other unidentified mechanisms in other DLBCL cells. However, Aiolos and Ikaros levels are slightly decreased in WSU-DLCL2 resistant cells compared to parental. Additionally, c-Myc levels are decreased in both WSU-DLCL2 and TMD8 resistant cells while CD44, a marker of aggressive disease, is increased in the ABC DLBCL cell line (TMD8).

In addition, WSU-DLCL2 (GCB) or Compound A-resistant WSU-DLCL2 (Cmp A-R) cells were treated with DMSO (control) or 1 or 10 μM lenalidomide or Compound A (Cmp A), and Aiolos and β-actin (control) levels were assessed by Western blot 24 or 72 hours later, essentially as described in Section 6.8.

As shown in FIG. 5B, the rate of destruction of Aiolos in the WSU-DLCL2 Cmp A-R (Compound A resistant) cell line is decreased compared to the parental cell line.

6.13 Dynamic Range of Expression Levels of CRBN, Aiolos and Ikaros in DLBCL Patients

Tumor cells were harvested an prepared from human patients, and immunohistochemistry to detect CRBN, Aiolos or Ikaros was performed, essentially as described in Section 6.9.

FIG. 6 depicts the dynamic range of expression levels of CRBN, Aiolos and Ikaros in DLBCL patients. IHC of a FFPE samples from 90 patients for CRBN, Aiolos and Ikaros indicates a wide range of expression levels in primary DLBCL. FIG. 6A shows the range of CRBN expression in three exemplary clinical trial patients, C4, F2 and B9. CRBN staining was observed in 76/90 cases (84%). Nuclear CRBN was observed in 23/76 positive CRBN tumors. FIG. 6B shows the range of Aiolos expression in two exemplary clinical trial patients, E2 and G4. Aiolos staining was observed in 85/90 cases (94%). Aiolos was strongly expressed in 61/85 patients. FIG. 6C shows the range of Ikaros expression in two exemplary clinical trial patients, E2 and G4. Ikaros staining was observed in 76/90 cases (84%).

The dynamic range of CRBN, Aiolos and Ikaros in DLBCL can be used as a positive inclusion process for participation in a Compound A (or other compound) clinical trial.

6.14 Differential Activity of Lenalidomide and Compound A

Lenalidomide and Compound A at varying concentrations from 1 to 100 μM were tested for their activity and effect on various diffuse large B-cell lymphoma (DLBCL) cell lines: SUDHL-10 (GCB), HT (GCB), Karpas 422 (GCB), WSU-DLCL2 (GCB), SUDHL-6 (GCB), Farange (GCB), OCI-Ly-3 (ABC), TMD8 (ABC), and OCI-Ly10 (ABC). The cells were then analyzed for proliferation using a ³H-thymidine incorporation assay.

FIG. 7 depicts the differential activity of lenalidomide and Compound A in GCB and ABC DLBCL. Multiple DLBCL cell lines were culture with either lenalidomide or Compound A for 3 days. Proliferation was assessed through tritiated thymidine incorporation. Three phenomena were observed; inherent resistance, differential activity of Compound A compared to Lenalidomide or a distinct potency difference between the two molecules. Differential activity of Compound A is observed in some GCB DLBCL compared to lenalidomide. However, Compound A is more potent than lenalidomide in ABC DLBCL

6.15 Lenalidomide Competes with Compound A and Compound C for CRBN

TMD8 (ABC) or Karpas 422 (GCB) cells were treated with either lenalidomide; Compound A; and 100 μM lenalidomide, 1-(3-chloro-4-methylphenyl)-3-((2-(2,6-dioxopiperidin-3-yl)-1-oxoisoindolin-5-yl)methyl)urea (Compound C (Cmp C)); or Compound C and 100 μM lenalidomide. They were cultured and cell-passaged long-term in lenalidomide or Compound A. The cells were then analyzed for proliferation using a ³H-thymidine incorporation assay.

FIG. 8 shows that lenalidomide competes with Compound A and Compound C for CRBN. FIG. 8A shows that co-treatment with Compound A and 10 μM lenalidomide blocks anti-proliferative effects of Compound A, though competition of binding to the CRBN complex. Likewise, FIG. 8B shows that co-treatment with Compound C and 10 μM lenalidomide blocks anti-proliferative effects of Compound C, though competition of binding to the CRBN complex. Co-culture of Lenalidomide with either Compound A or Compound C dampens the activity of these compounds as they target the same binding pocket with relative affinity.

6.16 Differentiation of Lenalidomide and Compound A in DLBCL Using TMT Mass Spectrometry

GCB cell lines (WSU-DLCL2, WSU-DLCL2-Cmp A-Resistant (Compound A resistant), Karpas 422 and HT) and ABC cell lines (TMD8, TMD8-Cmp A-Resistant, OCT-LY10 and U2932) were treated with either lenalidomide or Compound A for 24 or 72 hours. Aiolos or β-actin (control) protein levels were analyzed by Western blotting, essentially as described in Section 6.8. Proteins from these cells are also labeled and analyzed with Tandem Mass Tag proteomics to quantitatively measure differences in protein levels differentially affected by lenalidomide and Compound A.

FIG. 9 shows the differentiation of lenalidomide and Compound A in DLBCL using TMT mass spectrometry. Aiolos protein levels decrease in a dose-dependent manner in as little as 24 hours in both ABC and GCB DLBCL (bottom panels).

6.17 Compound a and shAiolos Induce IFN Response Proteins

U2932 (ABC) cells were cultured and cell-passaged long-term in Compound A as described in Section 6.10. Levels of Aiolos, IRF7, and β-actin (control) were assessed using Western blotting, essentially as described above in Section 6.8.

Karpas 422 (GCB) cells were transfected with negative control siRNA (luciferase) or Aiolos specific siRNA at a concentration of 0, or 10 ng/ml. After 72 hours, Aiolos, c-myc, IRF7, and β-actin (control) were measured by Western blot, essentially as described in Section 6.8. Alternatively, after 3 or 5 days, the cells were analyzed for proliferation using a ³H-thymidine incorporation assay.

FIG. 10A shows that Compound A up-regulates IFN response gene expression and upregulates IRF7 protein expression. FIG. 10B shows that shAiolos upregulates IRF7 protein expression.

6.18 Proteomic Screening Shows Compound A Affects CSNK1A1 Protein

(ABC-DLBCL) cell line was treated with either lenalidomide or Compound A for 24 and 72 hours. Cells were harvested and proteins were fractionated using a basic pH reverse gradient method. Fractionated samples were labeled using a Tandem Mass Tag method. Log 2 ratios, averaged across replicates, of 10 uM lenalidomide and 10 uM Compound A relative abundances against those of the 24 h DMSO control treatment after 24 h exposure are plotted against each other in FIG. 11. The regression line displayed has r2=0.752, gradient 1.45 and intercept 0.03, suggesting generally stronger effect of Compound A compared to lenalidomide at this concentration. The protein CSNK1A1 (Casein Kinase 1, alpha 1 or CK1α), located in the q32 region of chr5 commonly associated with the del5q MDS sub-type, stands out as one of few proteins affected by lenalidomide exposure to a manifestly greater extent than by Compound A.

Thus, it was shown that Compound A does not appear to affect CSNK1A1 protein, while Lenalidomide decreases it.

6.19 Lenalidomide, Pomalidomide, Compound A, or shAiolos Affects IFN Pathway

6.20 Proteomics Analysis Shows the Level of ZFP91 Reduces in Response to Treatment with Various Compounds in Lymphoma Cell Lines

Lymphoma cells from cells lines OCI-LY10, TMD8, and WSU-DLCL2, were treated with either DMSO, lenalidomide or Compound A for 24 and 72 hours. Cells were harvested and proteins were fractionated using a basic pH reverse gradient method. Fractionated samples were labeled using a Tandem Mass Tag (TMT) method. Relative abundance was calculated. Those proteins with decreased or increased relative abundance compared to DMSO control are listed in Table 1 below. As shown, the level of ZFP91 reduces in response to Compound A treatment in these lymphoma cell lines. The proteins upregulated or downregulated as shown in Table 1 can be used as a biomarker for selecting a patient for treatment with Compound A or for predicting/monitoring efficacy of Compound A in treating lymphomas according to the methods provided herein.

6.21 Western Analysis Shows the Levels of ZFP91 and Aiolos Reduce in Response to Treatment with Various Compounds in Lymphoma Cell Lines

OCI-LY10 cells treated with DMSO, 100 μM thalidomide, 10 μM lenalidomide, 1 μM pomalidomide, 1 μM Compound A, 10 μM Compound A, 100 μM Compound B, or 100 μM Compound C for 6 hours. Cells were harvested with RIPA buffer, and proteins from cell lysates were separated by 10% sodium dodecyl sulfate polyacrylamide (SDS-PAGE) gel electrophoresis (Bio-Rad), and transferred to PVDF membranes (Invitrogen). Immunoblots were probed with antibodies recognizing Aiolos (9-9-7; Celgene), CK1a (Abcam), GSPT1 (Sigma), ZFP91 (LSBio) and β-actin (Li-Cor). Signals were detected with a Li-Cor Odyssey imager. The results were shown in FIG. 14A, and as shown, the levels of ZFP91 and Aiolos reduce in response to treatment with various compounds in the lymphoma cells

OCI-LY10 cells treated with DMSO, 100 μM thalidomide, 10 μM lenalidomide, 1 μM pomalidomide, 1 μM Compound A, 10 μM Compound A, 100 μM Compound B, or 100 μM Compound C for 6 hours. Additionally, one sample was pretreated with 10 μM MLN-4924 for 1 hour prior to drug treatment with Compound A. Cells were harvested with RIPA buffer and Proteins from cell lysates were separated by 10% sodium dodecyl sulfate polyacrylamide (SDS-PAGE) gel electrophoresis (Bio-Rad), and transferred to PVDF membranes (Invitrogen). Immunoblots were probed with antibodies recognizing Aiolos (9-9-7; Celgene), GSPT1 (Sigma), ZFP91 (LSBio) and β-actin (Li-Cor). Signals were detected with a Li-Cor Odyssey imager. The results were shown in FIG. 14B. As shown, MLN-4924 blocked Aiolos and ZFP91 degradation in response to Compound A.

6.22 Western Analysis Shows the Level of ZFP91, CRBN, Ikaros, or Aiolos Changes in Response to Treatment with Compounds in Myeloma, Lymphoma, and Primary B Cell Lines

Multiple myeloma cells (U266, DF15, RPMI8226), diffuse large B cell lymphoma cells (OCI-LY10, WSU-DLCL2, WSU-DLCL2 Compound A resistant), and primary B cells were treated with DMSO, 1 mM pomalidomide or 1 mM Compound A for 8 hours. Cells were harvested and were treated in cell lysis buffer to generate cell lysates. Proteins from cell lysate were separated by gel electrophoresis (10% SDS-PAGE) and transferred to nitrocellulose membranes. Immunoblots were then probed with antibodies recognizing Aiolos, CRBN, Ikaros, ZFP91 (LSBio), IRF4, IRF7, Myc, and β-actin (Li-Cor). The results were shown in FIG. 15. As shown, in all these cell lines, treatment with compounds reduced the levels of Aiolos, Ikaros, and ZFP91.

6.23 Compounds Induce Reduction of ZFP91 Level in a CRBN Dependent Pathway in Multiple Myeloma Cells

As shown in FIG. 16A, pomalidomide induced ZFP91 degradation is CRBN dependent in U266 cells. U266 cells were transduced with inducible shRNA constructs targeting CRBN or targeting luciferase as control. Cells were grown in the presence or in the absence of 10 ng/ml Doxycycline, and in the presence or in the absence of 1 μM pomalidomide. Cells were harvested and were treated in cell lysis buffer to generate cell lysates. Proteins from cell lysate were separated by gel electrophoresis and transferred to nitrocellulose membranes. Immunoblots were then probed with antibodies recognizing Aiolos, CRBN, Ikaros, ZFP91, IRF4, IFIT1, IFIT3, P-STAT1, and β-actin (Li-Cor). As shown, when CRBN was knocked down by shRNA, the pomalidomide induced reductions of Aiolos, Ikaros, and ZFP91 were blocked.

Also as shown in FIG. 16B, thalidomide, lenalidomide, pomalidomide, or Compound A induced destruction of Aiolos, Ikaros, and ZFP91 in a CRBN dependent pathway. CRBN shRNA expression was induced for 48 hours in U266 cells with 10 ng/ml doxycycline prior to a 6 hour compound treatment (using DMSO, 100 mM thal, 10 mM len, 1 mM pom, or 1 mM Compound A). Cells were harvested, and lysates were run on 10% SDS-PAGE and immunoblotted with the appropriate antibodies. As shown, when CRBN was down regulated, reduction of Aiolos, Ikaros, and ZFP91 proteins induced by the compounds was blocked.

Similarly, when NAE1 or proteasome inhibitors were used to treat the cells, the compounds induced reduction of Aiolos, Ikaros, and ZFP91 proteins was blocked, as shown in FIG. 16C. MG132 activates c-Jun N-terminal kinase (JNK1), which initiates apoptosis. MG132 also inhibits NF-κB activation with an IC50 of 3 μM and prevents β-secretase cleavage. MLN4924 is a NAE1 inhibitor that blocks the activity of Cullin Ring Ligases (CRLs), such as CRL4^(CRBN). U266 cells were pretreated with 10 mM MLN4924 or MG132 for 1 hr and then compounds were added for 6 hr (DMSO, 100 mM thal, 10 mM len, 1 mM pom, 1 mM Compound A, or 0.1 mM Compound B). Cells were harvested and lysates were run on 10% SDS-PAGE, transferred to nitrocellulose and immunoblotted with the corresponding antibodies. As shown, when CRBN activity was inhibited, reduction of Aiolos, Ikaros, and ZFP91 proteins induced by the compounds (thalidomide, lenalidomide, pomalidomide, or Compound A) was blocked. The results indicate that ZFP91 is a substrate of CRBN and ZFP91 is down-regulated in response to the compounds provided herein in a CRBN dependent pathway.

6.24 Compounds Induce Reduction of ZFP91 Level in a CRBN Dependent Pathway in Diffuse Large B Cell Lymphoma Cells

OCI-LY10 cells treated with DMSO or various drugs for 6 hrs. Cells were harvested with RIPA buffer and proteins from cell lysates were separated by 10% sodium dodecyl sulfate polyacrylamide (SDS-PAGE) gel electrophoresis (Bio-Rad), and transferred to PVDF membranes (Invitrogen). Immunoblots were probed with antibodies recognizing: Aiolos (9-9-7; Celgene), CK1a (Abcam), GSPT1 (Sigma), ZFP91 (LSBio) and β-actin (Li-Cor). Signals were detected with a Li-Cor Odyssey imager. The results were shown in FIG. 17A-B. As shown in FIG. 17A, 100 mM thalidomide, 10 mM lenalidomide, 1 mM pomalidomide, 1 μM or 10 μM Compound A, or 100 nM Compound B reduced the levels of ZFP91 and Aiolos in OCI-LY10 cells. As shown in FIG. 17B, 1 μM lenalidomide, 10 μM lenalidomide, 0.1 μM Compound A, 1 μM Compound A, and 10 μM Compound A reduced the levels of ZFP91 and Aiolos.

OCI-LY10 cells were then treated with DMSO or various drugs for 6 hrs. Additionally, one sample was pretreated with 10 μM MLN-4924 for 1 hour prior to drug treatment. Cells were harvested with RIPA buffer and Proteins from cell lysates were separated by 10% sodium dodecyl sulfate polyacrylamide (SDS-PAGE) gel electrophoresis (Bio-Rad), and transferred to PVDF membranes (Invitrogen). Immunoblots were probed with antibodies recognizing: Aiolos (9-9-7; Celgene), ZFP91 (LSBio), ZNF198 (LSBio) and β-actin (Li-Cor). Signals were detected with a Li-Cor™ Odyssey imager. The results were shown in FIG. 17C, and as shown, pre-treatment by MLN-4924 restored the level of both Aiolos and ZFP91.

OCI-LY10 cells stably transduced with shCRBN 11 were induced for 48 hrs with either 0 or 10 ng/ml of doxycycline. Cells were then treated with either DMSO, lenalidomide, or Compound A for an additional 6 hours. Where MLN4924 treatments were present, MLN4924 was pre-incubated for 1 hr prior to drug treatment. Cells were harvested with RIPA buffer and Proteins from cell lysates were separated by 10% sodium dodecyl sulfate polyacrylamide (SDS-PAGE) gel electrophoresis (Bio-Rad), and transferred to PVDF membranes (Invitrogen). Immunoblots were probed with antibodies recognizing: CRBN-65, Aiolos (9-9-7; Celgene), Ikaros (Millipore), ZFP91 (LSBio) and β-actin (Li-Cor). Signals were detected with a Li-Cor Odyssey imager. The results were shown in FIG. 17D. Again, as shown, pre-treatment by MLN-4924 restored the level of both Aiolos and ZFP91 in cells treated with all the compounds tested, indicating that these compounds induce reduction of ZFP91 level in a CRBN dependent pathway in diffuse large B cell lymphoma cells.

6.25 Dual Staining Immunohistochemistry Assay for Measuring CRBN-Associated Proteins

This example exemplifies using dual staining immunohistochemistry (IHC) to measure CRBN, Aiolos and Ikaros proteins. Dual staining immunohistochemistry was performed on the Bond-Max automated slide stainer (Leica Microsystems) using Bond Polymer Refine Detection Kit and Bond Polymer Refine Red Detection Kit. Multiple myeloma cell model (DF15, pomalidomide-resistant DF15R, and U266 CRBN shRNA) and 25 cases of commercially available multiple myeloma patient bone marrow clots or biopsies were used in the assay. Formalin-fixed paraffin-embedded (FFPE) tissues or cell pellets were sectioned and deparaffinized on the instrument. Antigen retrieval was performed with Epitope Retrieval 2 (pH 9.0) for 20 minutes at 100° C. The slides were blocked for endogenous peroxidase activity with Peroxide Block for 5 minutes at room temperature. Sections were then incubated with a first antibody—rabbit monoclonal antibody to CRBN (CGN-6-4-5 available from Celgene), rabbit monoclonal antibody to Aiolos (9B-9-7 available from Celgene), or rabbit polyclonal antibody to Ikaros (Santa Cruz, sc-13039), for 15 minutes at room temperature, followed by incubation with HRP labeled Polymer for 8 minutes at room temperature. The sample was treated with hydrogen peroxide substrate and diaminobenzidine tetrahydrochloride (DAB) chromogen at room temperature for 10 minutes, and then in bound Wash buffer at 90° C. for 5 minutes. The sections were then incubated with an anti-CD128 mouse monoclonal antibody (Dako, M7228) for 15 minutes, followed by incubation with AP labeled Polymer for 8 minutes at room temperature. The sample was treated with hydrogen peroxide substrate and Refine Red at room temperature for 10 minutes. Slides were counterstained with Hematoxylin for 5 minutes at room temperature. Slides were then analyzed under light microscope and final scores were assigned using 40× objective.

Results were analyzed using H-score method. The H-score is a method of assessing the extent of immunoreactivity. The score is obtained by the formula: 3×percentage of strongly staining cells+2×percentage of moderately staining cells+1×percentage of weakly staining cells+0×percentage of negative staining cells, which gives a range of 0 to 300. The entire area of viable sample is scored for maker immunoreactivity based on the distribution and intensity. Scoring was given to those samples with 20 or more well-preserved CD128 positive cells, and areas compromised by artifact, e.g., edge staining, folding, shrinking, smearing, and incomplete fixation, are avoided.

As shown in Table 2 below, dual staining immunohistochemistry detected a range of CRBN levels in 22 MM cases.

TABLE 2 CRBN Levels Detected by Dual Staining Immunohistochemistry Average Cytoplasmic Average nuclear Average total Sample No. H-score H-score H-scores MM12 193 213 407 MM13 150 193 343 MM14 207 177 383 MM15 183 180 363 MM16 240 250 490 MM17 100 110 210 MM18 267 233 500 MM19 163 100 263 MM20 67 17 83 MM21 240 193 433 MM22 110 127 237 MM23 217 240 457 MM24 190 173 363 MM25 93 40 133 MM26 117 87 203 MM27 137 160 297 MM28 83 110 193 MM30 63 50 113 MM33 137 87 223 MM34 177 157 333 MM35 80 47 127 MM36 67 40 107

As shown in FIG. 18, pathologic evaluation of 22 MM samples using the dual assay and the H-score method demonstrated high concordance in H-scores.

As shown in FIG. 19A, the dual staining assay differentiated high and low CRBN expression levels in multiple myeloma cell line DF15 and pomlidomide-resistant DF15R, respectively. FIG. 19B shows the CRBN staining results and H-score for Sample MM12. FIG. 19C shows the CRBN staining results and H-score for Samples MM13 and MM15.

FIG. 20 and FIG. 21 shows the Aiolos staining and nuclear H-score and Ikaros staining and nuclear H-score, respectively, in Sample MM23.

As shown, these results demonstrate that dual staining immunohistochemistry assay can accurately measure a broad range of immunoreactivity. The dual CD138/CRBN, CD138/Aiolos, and CD138/Ikaros immunohistochemistry assays are effective in both bone marrow core biopsies and aspirate clots from 22 MM patients, for detection of a range of CRBN, Aiolos and Ikaros levels, respectively. Pathologic evaluation of MM samples using the dual assay and the H-score method demonstrated high concordance in H-scores. Thus, dual staining immunohistochemistry assay provides reliable and accurate semi-quantitative methods to evaluate CAPs in a cancer patient.

6.26 Lenalidomide Promotes Degradation of Casein Kinase 1α (CSNK1A1 or CK1α) in MDS and AML Cells

Sensitivity to lenalidomide treatment in a panel of myeloid cancer cell lines was evaluated by tritiated thymidine and/or BrdU assays. 13 MDS/AML and 1 MM cell lines were evaluated for sensitivity to lenalidomide (LEN) in a 4 d BrdU cell assay. The results are shown in FIG. 22A, and as shown, across a panel of myeloid cancer cell lines evaluated for sensitivity to lenalidomide, HNT-34 and MDS-L cells show the greatest sensitivity to lenalidomide, with EC50's of 0.6 and 1.5 uM, respectively, while other cell lines were predominantly insensitive (EC50>10 uM). As shown in FIG. 22B, both HNT-34 and MDS-L cells were sensitive to lenalidomide, while only MDS-L cells were sensitive to Compound A, indicating of the selectivity of these compounds. As shown in FIG. 22C, the sensitivity of myeloid cancer cell lines to lenalidomide (LEN) and Compound A. As shown in FIG. 22D, lenalidomide promotes the degradation of casein kinase 1, alpha 1(CSNK1A1; also interchangeably referred to as “CK1a” and “CK1α” herein) in the sensitive cell lines (HNT-34, MDS-L), but does not degrade CSNK1A1 in the insensitive line (e.g., MOLM-13, THP). Lenalidomide also promoted degradation of CSNK1A1 in the insensitive cell lines KG-1 and HL-60. FIG. 23E shows a Western Blot analysis of CK1α, Ikaros, and CRBN protein levels in untreated and lenalidomide (LEN)-treated myeloid cancer cells.

As shown in FIG. 23E, CK1α and Ikaros levels were reduced in LEN-treated myeloid cancer cell lines in vitro. In particular, decreased CK1α and Ikaros protein levels with LEN treatment were confirmed in MDS-L and HNT-34 cells. Decreased CK1α protein levels with LEN treatment were also observed in KG-1 and HL-60, but not in THP-1 or MOLM-13 AML cells. Decreased Ikaros protein levels with LEN treatment were also observed in KG-1, but not in THP-1 cells; HL-60 and MOLM-13 cells did not express detectable Ikaros. In addition, CRBN was expressed at higher levels in MDS-L, HNT-34, and KG-1 versus HL-60, THP-1, and MOLM-13 cells.

Changes in global cellular protein levels were measured by tandem-mass-tagged proteomics in a del(5q) MDS cell line (MDS-L) and an AML cell line (HNT-34), following treatment with vehicle or 10 uM lenalidomide or 1 uM Compound A for 8, 24 and 72 hours. Samples were subjected to multiplexed quantitative mass spectrometry analysis. In particular, cell lysate was prepared from the samples, and was subjected to tandem protein digestion using LysC and trypsin, peptide labeling with either Tandem Mass Tag 6-plex or 10-plex reagents, and peptide fractionation. Multiplexed quantitative mass spectrometry data were collected on an Orbitrap Fusion mass spectrometer operating in a MS3 mode using synchronous precursor selection for the MS2 to MS3 fragmentation. MS/MS data were searched against a Uniprot human database with both the forward and reverse sequences using the SEQUEST algorithm. Additional data processing steps included controlling peptide and protein level false discovery rates, assembling proteins from peptides, and protein quantification from peptides. Each drug-treated sample has 3 replicates, each DMSO sample has 4 replicates.

Protein levels were measured by tandem-mass-tagged proteomics in a del(5q) MDS cell line (MDS-L), following treatment with vehicle or 10 uM lenalidomide for 8, 24 and 72 hours (data not shown). Protein levels were also measured by tandem-mass-tagged proteomics in an AML cell line (HNT-34), following treatment with vehicle or 10 uM lenalidomide for 8, 24 and 72 hours (data not shown).

Selected results of proteomics studies are shown in Tables 3-8. The average relative abundance of the protein is shown in the tables. T is the statistic calculated for the t.test. P.value represents statistical significance for the test. Adj.P.value represents FDR multiple testing correction of the P.values in previous parameter. B log odds that the protein is differentially abundant between the conditions (compound vs control).

Proteomic analysis of lenalidomide-regulated proteins showed that CSNK1A1 and Ikaros were down-regulated in response to lenalidomide treatment, as shown in FIG. 23A (bars correspond to the average log 2 fold-change of 3 replicates and error bars correspond to 95% confidence interval for the mean). Proteomic analysis of lenalidomide-regulated proteins in MDS-L cells revealed Ikaros as the most down-regulated protein at 72 hrs (about 5 fold), and CSNK1A1 was the second most down-regulated protein (about 3 fold), as shown in FIG. 23B.

Western blot analysis was used to subsequently validate proteins that were differentially regulated in these lenalidomide-sensitive cell lines. The decrease of Ikaros and CSNK1A1 proteins by lenalidomide were confirmed by Western blot analysis in MDS-L cells as shown in FIG. 23C. The decrease of Ikaros and CSNK1A1 proteins by lenalidomide were also confirmed by Western blot analysis in HNT-34 cells as shown in FIG. 23C. As shown in FIG. 24, degradations of CSNK1A1 and Ikaros in HNT-34 cells treated with lenalidomide were time- and dose-dependent.

Mechanistic studies addressing CSNK1A1 regulation in HNT-34 cells revealed that CSNK1A1 protein levels were reduced by lenalidomide treatment in a time- and dose-dependent manner, with maximal reduction of 3.3-fold observed at 4 hrs using 10 uM lenalidomide, and CSNK1A1 degradation observed with lenalidomide at a dose as low as 0.1 uM, as shown in FIG. 24.

The effects of lenalidomide on CSNK1A1 level were validated in clinical studies. Five patients with acute myeloid leukemia (not previously treated and age 65 or older) were treated with 50 mg lenalidomide daily, and bone marrow or blood samples were obtained from the patients and processed to bone marrow mononuclear cells (BMMC) or peripheral blood mononuclear cells (PBMC). 3-5 μg total protein from each sample was evaluated for CSNK1A1, Ikaros, and GAPDH expressions by western analysis. The results were shown in FIG. 25. As shown In FIG. 25A, both CSNK1A1 and Ikaros were modulated (down-regulated) in 4 of 5 patients treated with lenalidomide. In addition, FIG. 25B shows that CK1α and Ikaros protein levels were reduced in bone marrow or peripheral blood of lenalidomide (LEN)-treated patients with AML in vivo.

6.27 MG-132 or Compound a Pre-Treatment Blocks Lenalidomide-Induced Degradation of CK1a and IKAROS in HNT-34 Cells

HNT-34 cells were pre-treated with or without 3 μM or 10 μM MG-132 for 30 min. Then cells were treated with 10 μM lenalidomide for 3 h or 6 h. The results were shown in FIG. 26, and as shown lenalimoide treatment decreased both CSNK1A1 and Ikaros proteins levels at 3 h or 6 h, and pre-treating HNT-34 cells with the proteasome inhibitor MG-132 stabilized CSNK1A1 protein levels in the presence of lenalidomide, demonstrating proteasome-dependent degradation.

A competition experiment performed by pre-treating HNT-34 cells with Compound A. HNT-34 cells were pre-treated with 10 μM Compound A for 1.5 h. Then cells were treated with 0.1-10 μM lenalidomide for 3 h or 6 h. Western analysis of Ikaros and CSNK1A1 were shown in FIG. 27. As shown in FIG. 27A, 10 μM Compound A blocks 0.3 μM or less lenalidomide induced CSNK1A1 degradation at 3 h or 6 h. Compound A binds CRBN, and as a result, CSNK1A1 protein is stabilized in the presence of lenalidomide, demonstrating CRBN-dependence of the lenalidomide-induced degradation. FIG. 27B shows that the LEN-mediated reduction of CK1α levels are cullin-dependent and CRBN-dependent. For example, pretreatment with proteosome inhibitor (MG-132) and neddylation inhibitor (MLN-4924) abrogated LEN-mediated CK1α reduction in HNT-34 cells (FIG. 27B, left panel). In addition, pretreatment with CRBN RNAi inhibited LEN-mediated CK1α reduction in HNT-34 cells (FIG. 27B, right panel).

These results indicate that CSNK1A1 is a lenalidomide-induced substrate of CRL4-CRBN. As the CSNK1A1 gene is located at 5q32, a commonly deleted region in MDS, further reduction of haplo-insufficient expression of CSNK1A1 is a potential mechanism of sensitivity to lenalidomide in del(5q) MDS.
